 Chapter 22             

IP

IP (Internet Protocol) is an identifier for a computer or device on a TCP/IP network. Networks using the TCP/IP protocol route messages based on the IP address of the destination. The format of an IP address is a 32-bit numeric address written as four numbers separated by periods. Each number can be 0 to 255. For example: 10.5.25.180.

Every computer that communicates over the Internet is assigned an IP address that uniquely identifies the device and distinguishes it from other computers on the Internet. Within an isolated network, IP addresses can be assigned at random as long as each one is unique. However, to connect a private network to the Internet, the registered IP addresses must be used (called Internet addresses) to avoid duplicates. The four numbers in an IP address are used in different ways to identify a particular network and a host on that network.

Four regional Internet registries -- ARIN, RIPE NCC, LACNIC and APNIC -- assign Internet addresses from the following three classes.

      Class A - supports 16 million hosts on each of 126 networks

      Class B - supports 65,000 hosts on each of 16,000 networks

      Class C - supports 254 hosts on each of 2 million networks

The number of unassigned Internet addresses is running out, so a new classless scheme called CIDR (Classless Inter-Domain Routing) is gradually replacing the system based on classes A, B, and C and is tied to adoption of IPv6.

ICMP (Internet Control Message Protocol) is an extension to the IP defined by RFC 792. ICMP supports packets containing error, control, and informational messages. For example, the ping command uses ICMP to test an Internet connection.

Oracle SEFOS provides the flexibility to use either the Oracle IPv4 Module or the Linux IP. The IP commands under this section are therefore classified into:

22.1        Commands Specific for Oracle IP

This section describes the commands that are specific for Oracle IP alone. These commands are based on the Oracle Proprietary MIB.

22.1.1     ip redirects

 

Command Objective

This command enables sending ICMP redirect messages. The redirect message is an ICMP message which informs a host to update its routing information to send packets on an alternate route when a packet enters an IP interface and exits the same interface. The redirect message is sent to inform the host of the presence of alternative route.

The no form of this command disables sending ICMP redirect messages.

Syntax

ip redirects [vrf <vrf-name>]

no ip redirects [vrf <vrf-name>]

Parameter Description

      vrf <vrf-name> - Sends the ICMP redirect messages for the specified VRF instance. This value represents unique name of the VRF instance. This value is a string of maximum size 32.

Mode

Global Configuration Mode

Package

Workgroup, Enterprise, Metro_E,  and Metro

Default

Sending of ICMP Redirect messages is enabled.

Note:      

VRF instance should be created before executing this command to configure ICMP redirect messages for the context.

Example

SEFOS(config)# ip redirects

Related Command(s)

      ip vrf - Creates VRF instance.

      show ip information -– Displays IP configuration information.

 

22.1.2     ip unreachables

 

Command Objective

This command enables the router to send an ICMP unreachable message to the source if the router receives a packet that has an unrecognized protocol or no route to the destination address. ICMP provides a mechanism that enables a router or destination host to report an error in data traffic processing to the original source of the packet. This informs the source that the packet is dropped.

The no form of this command disables sending ICMP unreachable messages.

22.1.6     ip rarp client request

 

Command Objective

This command sets the number of RARP client request retries or interval between requests. The ip rarp client request is sent from a newly set up machine in a network. The RARP client program requests the RARP server in the router to send its IP address. The network administrator creates a table in the LAN’s gateway router. The router maps the MAC address of the client to an IP address that is sent to the client for future use. If the server didn’t respond with an IP address, the client retries the request for the configured number of times and the interval between each retry can also be set.

The no form of this command sets the RARP client request retries or interval between retries to the default values.

RARP requests are most commonly sent by diskless clients and JumpStart clients during boot. The client uses the RARP protocol to broadcast the Ethernet address and asks for the corresponding IP address.

Syntax

ip rarp client request {interval <timeout (30-3000)> | retries <retries (2-10)>}

no ip rarp client request { interval|retries }

Parameter Description

      interval  <timeout (30-3000)> - Configures the interval (in seconds) after which an unanswered RARP request is transmitted. This value ranges from 30 to 3000.

      retries <retries (2-10)> - Sets the maximum number of retransmissions of RARP request packet after which request must not be sent. This value ranges from 2 to 10.

Mode

22.1.7     ip aggregate-route

 

Command Objective

This command sets the maximum number of aggregate routes. Aggregate Route-based IP switching is achieved by creating a virtual circuit along the network by selecting the forwarding paths used by routers that use OSPF and BGP(Border Gateway Protocol).The data is sent through these virtual circuits to the destination. The routing process is skipped along this circuit. The data is tagged with a label that is read by the switches and forwarded to the destination. This value ranges from 5 to 4095.

The no form of this command sets the maximum number of aggregate routes to its default value.

Syntax

ip aggregate-route <value (5-4095)>

no ip aggregate-route

22.1.8     traffic-share

 

Command Objective

This command enables traffic sharing (load sharing of IP packets). Traffic sharing is the process by which the protocols select the route for traffic flow with regard to path cost calculation and load distribution. EIGRP (Enhanced Interior Gateway Routing Protocol) provides intelligent traffic sharing. Traffic sharing is controlled by selecting the mode of distribution. The traffic-share balanced distributes the traffic proportionately to the ratio of the metrics of different routes. The traffic-share min distributes the traffic in the route which has minimal cost path even if different paths are available.

The no form of this command disables traffic sharing.

Note:      

This command is currently not supported on Broadcom chipsets.

IPv6

IPv6 is a new version of IP which is designed to be an evolutionary step from IPv4. (Internet Protocol Version 6 is abbreviated to IPv6 (where the “6” refers to the assigned version number 6). The previous version of the Internet Protocol is version 4 (referred to as IPv4).

IPv6 can be installed as a normal software upgrade in Internet devices and is interoperable with the current IPv4. It has expanded routing and addressing capabilities because of the 128 bit addressing as compared to the 32 bit addressing in IPv4. Its deployment strategy is designed to not have any flag days or other dependencies. IPv6 is designed to run well on high performance networks (e.g. Gigabit Ethernet, OC-12, ATM, and so on) and at the same time still be efficient for low bandwidth networks (e.g. wireless). In addition, it provides a platform for new Internet functionality that will be required in the near future.

IPv6 includes a transition mechanism, which is designed to allow users to adopt and deploy IPv6 in a highly diffused fashion, and to provide direct interoperability between IPv4 and IPv6 hosts. The IPv6 transition allows the users to upgrade their hosts to IPv6, and the network operators to deploy IPv6 in routers, with very little coordination between the two.

The changes from IPv4 to IPv6 fall primarily into the following categories

      Expanded Routing and Addressing Capabilities

      Usage of Anycast address

      Header Format Simplification

      Improved Support for Options

      Quality-of-Service Capabilities

      Authentication and Privacy Capabilities

23.30     show ipv6 traffic

 

Command Objective

This command displays the IPv6 ICMP and UDP statistics.

Syntax

show ipv6 traffic [vrf <vrf-name>] [interface { vlan <vlan-id/vfi-id> | tunnel <tunnel-id> | <interface-type> <if-num> | <IP-interface-type> <IP-interface-number>} ] [hc]

Parameter Description

      vrf<vrf-name> - Displays the IPv6 ICMP and UDP statistics for the specified VRF instance. This value represents unique name of the VRF instance. This value is a string of maximum size 32.

      vlan <vlan-id/vfi-id> - Displays the IPv6 ICMP and UDP statistics for the specified VLAN / VFI ID. This value ranges from 1 to 65535.

   <vlan –id> - VLAN ID is a unique value that represents the specific VLAN. This value ranges from 1 to 4094.

   <vfi-id> - VFI ID is a VLAN created in the system which contains pseudowires and attachment circuits as member ports. This creates a logical LAN for the VPLS service. This value ranges from 4096 to 65535.

Note:     The VLAN ID 4095 is reserved and may be used to indicate a wildcard match for the VID in management operations or filtering database entries.

Note:     VFI IDs 4096 and 4097 are reserved identifiers used in MPLS PW.

Note:     The theoretical maximum for the maximum number of VFI is 65535 but the actual number of VFI supported is a sizing constant. Based on this, the maximum number of VFI ID accepted in the management interface is restricted. For example if 100 VFIs are supported, the maximum number of VFI supported will be restricted to a hundred added to the maximum number of VLANs. An error message is displayed for any value beyond this range.

      tunnel-id <tunnel-id> - Displays the IPv6 ICMP and UDP statisticsfor the specified tunnel ID. The tunnel ID value ranges between 0 and 128.

      <interface-type>  - Displays the IPv6 ICMP and UDP statistics for the specified type of interface. The interface can be:

   fastethernet – Officially referred to as 100BASE-T standard. This is a version of LAN standard architecture that supports data transfer upto 100 Megabits per second.

   XL-ethernet – A version of LAN standard architecture that supports data transfer upto 40 Gigabits per second.

   extreme-ethernet – A version of Ethernet that supports data transfer upto 10 Gigabits per second.

   i-lan– Internal LAN created on a bridge per IEEE 802.1ap.

      <if-num> - Displays the IPv6 ICMP and UDP statistics for the specified interface identifier. This is a unique value that represents the specific interface. This value is a combination of slot number and port number separated by a slash, for interface type other than i-lan. For example: 0/1 represents that the slot number is 0 and port number is 1. Only i-lan ID is provided, for interface types i-lan. For example: 1 represents i-lan ID.

      <IP-interface-type> - Displays the IPv6 ICMP and UDP statistics for the specified L3 pseudowire interface in the system.

      <IP-interface-number> - Displays the IPv6 ICMP and UDP statistics for the specified L3 pseudowire interface identifier.  This is a unique value that represents the specific interface. This value ranges from 1 to 65535 for pseudowire interface.

Note:     Maximum number of pseudowire interfaces supported in the system is 100.

      hc - Displays the High counters for the ping messages.

 Chapter 24             

OSPF

OSPF (Open Shortest Path First ) protocol, is an Interior Gateway Protocol used to distribute routing information within a single Autonomous System. Routers use link-state algorithms to send routing information to all nodes in an inter-network by calculating the shortest path to each node based on topography of the Internet constructed by each node. Each router sends that portion of the routing table (keeps track of routes to particular network destinations) which describes the state of its own links, and it also sends the complete routing structure (topography).

The advantage of shortest path first algorithms is that they result in smaller, more frequent updates everywhere. They converge quickly, thus preventing problems like routing loops and Count-to-Infinity (when routers continuously increment the hop count to a particular network). This makes for a stable network.

Before configuring OSPF, RRD must be enabled. This can be done by defining RRD_WANTED in LR/make.h in compilation. In addition, all OSPF interface-related configurations can be done only when the global OSPF is enabled.

The list of CLI commands for the configuration of OSPF is common to both Single Instance and Multiple Instance except for a difference in the prompt that appears for the Switch with Multiple Instance support.
The prompt for the Global Configuration Mode is,
SEFOS(config)#

The parameters specific to Multiple Instance are stated so, against the respective parameter descriptions in this document.

The outputs of the show commands differ for Single Instance and Multiple Instance. Hence both the outputs are documented while depicting the show command examples.

24.31     network

 

Command Objective

This command defines the interfaces on which OSPF runs and the area ID for those interfaces. When a more specific OSPF network range is removed, interfaces belonging to that network range will be retained and remain active if and only if a less specific network range exists. There is no limit to the number of network commands that can be used on the router. The IP address for the entry should be same as that of the configured interface.

The no form of the command disables OSPF routing for interfaces defined and removes the area ID of that interface.

Note:      

When OSPF routing is enabled using the network command, the session established is properly mapped with the interface only if the interface administrative status is up. This is because to enable OSPF in an interface, both IP address and interface index are used.

Syntax

network <Network number> area <area-id> [unnum { Vlan <vlan-id/vfi-id> | <interface-type> <interface-num> | <IP-interface-type> <IP-interface-number>}]

no network <Network number> area <area-id> [unnum { Vlan <vlan-id/vfi-id> | <interface-type> <interface-num> | <IP-interface-type> <IP-interface-number>}]

Parameter Description

      <Network number> - Configures the network type for the interfaces.

      <area-id> - Configures the area associated with the OSPF address range and the identifier of the area about which routes are to be summarized. It can be specified as either a decimal value or as an IP address.

   <vlan –id> - VLAN ID is a unique value that represents the specific VLAN. This value ranges from 1 to 4094.

   <vfi-id> - VFI ID is a VLAN created in the system which contains pseudowires and attachment circuits as member ports. This creates a logical LAN for the VPLS service. This value ranges from 4096 to 65535.

Note:     The VLAN ID 4095 is reserved and may be used to indicate a wildcard match for the VID in management operations or filtering database entries.

Note:     VFI IDs 4096 and 4097 are reserved identifiers used in MPLS PW.

Note:     The theoretical maximum for the maximum number of VFI is 65535 but the actual number of VFI supported is a sizing constant. Based on this, the maximum number of VFI ID accepted in the management interface is restricted. For example if 100 VFIs are supported, the maximum number of VFI supported will be restricted to a hundred added to the maximum number of VLANs. An error message is displayed for any value beyond this range.

      <interface-type>  - Configures the network type for the specified type of interface. The interface can be:

   fastethernet – Officially referred to as 100BASE-T standard. This is a version of LAN standard architecture that supports data transfer upto 100 Megabits per second.

   extreme-ethernet – A version of Ethernet that supports data transfer upto 10 Gigabits per second.

   i-lan – Internal LAN created on a bridge per IEEE 802.1ap.

      <interface-num> - Configures the network type for the specified interface identifier. This is a unique value that represents the specific interface. This value is a combination of slot number and port number separated by a slash, for interface type other than i-lan. For example: 0/1 represents that the slot number is 0 and port number is 1. Only i-lan ID is provided, for interface types i-lan. For example: 1 represents i-lan ID.

      <IP-interface-type> - Configures the network type for the specified L3 pseudowire interface in the system.

      <IP-interface-number> - Configures the network type for the specified L3 pseudowire interface identifier.  This is a unique value that represents the specific interface. This value ranges from 1 to 65535 for pseudowire interface.

24.41     ip ospf cost

 

Command Objective

This command explicitly specifies the cost of sending a packet on an interface. The link-state metric is advertised as the link cost in the router link advertisement.

The no form of the command resets the path cost to the default value.

In general, the path cost is calculated using the following formula:

      108 / bandwidth

Using this formula, the default path costs are calculated. For example:

      56 Kbit/sec serial link - Default cost is 1785

      Ethernet - Default cost is 10

Syntax

ip ospf cost <cost (1-65535)> [tos <tos value (0-30)>]

no ip ospf cost [tos <tos value (0-30)>]

Parameter Description

      <cost (1-65535)> - Configures the Type 1 external metrics which are expressed in the same units as OSPF interface cost. That is, in terms of the OSPF link state metric. This value ranges from 1 to 65535.

      tos <tos value (0-30)> - Configures the Type of Service of the route being configured. This value ranges from 0 to 30. This parameter can be configured only if the code is compiled with TOS Support

24.42     ip ospf network

 

Command Objective

This command configures the OSPF network type to a type other than the default for a given media and configures broadcast networks as NBMA networks. Each pair of routers on a broadcast network is assumed to be able to communicate directly. An Ethernet is an example of a broadcast network. A 56 Kbit serial line is an example of a point-to-point network.

The no form of the command sets the OSPF network type to the default type.

Syntax

ip ospf network {broadcast | non-broadcast | point-to-multipoint | point-to-point}

no ip ospf network

Parameter Description

      broadcast - Configures the broadcast networks supporting many (more than two) attached routers, along with with the capability to address a single physical message to all of the attached routers (broadcast)

      non-broadcast - Configures the non-broadcast networks supporting many (more than two) routers, but having no broadcast capability. Sets the network type to non-broadcast multiaccess (NBMA).

      point-to-multipoint - Sets the network type to point-to-multipoint and treats the non-broadcast network as a collection of point-to-point links.

      point-to-point - Sets the network type to point-to-point that joins a single pair of routers.

24.43     ip ospf authentication-key

 

Command Objective

This command specifies a password to be used by neighboring routers that are using the OSPF simple password authentication. The password created by this command is used as a key  that is inserted directly into the OSPF header when the routing protocol packets are originated. The size of the password is 8 bytes. The password string can contain 1 to 8 uppercase and lowercase alphanumeric characters. A separate password can be assigned to each network on a per-interface basis. All neighboring routers on the same network must have the same password to be able to exchange OSPF information.

The no form of the command removes a previously assigned OSPF password.

24.44     ip ospf message-digest-key

 

Command Objective

This command enables OSPF MD5 authentication.  One key per interface is used to generate authentication information when sending packets and to authenticate incoming packets.

The no form of the command removes an old MD5 key.

      Message Digest authentication is a cryptographic authentication. A key (password) and key-ID are configured on each router. The router uses an algorithm based on the OSPF packet, the key, and the key-ID to generate a "message digest" that gets appended to the packet.

      Usually, one key per interface is used to generate authentication information when sending packets and to authenticate incoming packets. The same key identifier on the neighbor router must have the same key value.

Syntax

ip ospf message-digest-key <Key-ID (0-255)> [{ md5 | sha-1 | sha-224 | sha-256 | sha-384 | sha-512}]  <Key (16)>

no ip ospf message-digest-key <Key-ID (0-255)>

Parameter Description

      <Key-ID(0-255)> - Configures the secret key, which is used to create the message digest appended to the OSPF packet. This value ranges from 0 to 255.

      md5 - Sets the authentication type as Message Digest 5 (MD5) authentication.

      sha-1 - Sets the authentication type as Secure Hash Algorithm 1 (SHA1) authentication. SHA1 generates Authentication digest of length 20 bytes.

      sha-224 - Sets the authentication type as Secure Hash Algorithm 224 (SHA224) authentication. SHA224 generates Authentication digest of length 28 bytes.

      sha-256 - Sets the authentication type as Secure Hash Algorithm 256 (SHA256) authentication. SHA256 generates Authentication digest of length 32 bytes.

      sha-384 - Sets the authentication type as Secure Hash Algorithm 384 (SHA384) authentication. SHA384 generates Authentication digest of length 48 bytes.

      sha-512 - Sets the authentication type as Secure Hash Algorithm 512 (SHA512) authentication. SHA512 generates Authentication digest of length 64 bytes.

      <key (16)> - Configures the cryptographic key value which is used to create the message digest appended to the OSPF packet. All neighboring routers on the same network must have the same key identifier and key to route OSPF traffic. This is a string with maximum string size 16.

24.51     show ip ospf - retransmission-list

 

Command Objective

This command displays a list of all OSPF Link state retransmission list information waiting to be resent. This value is also used while retransmitting database description and link-state request packets.

Syntax

show ip ospf [vrf <name>] retransmission-list [<neighbor-id>] [{ vlan <vlan-id/vfi-id> | <interface-type> <interface-id> | <IP-interface-type> <IP-interface-number>}]

Parameter Description

      vrf<name> - Displays OSPF for the specified VRF instance. This value represents unique name of the VRF instance. This value is a string with maximum size 32.

      <neighbor-id> - Configures the neighbor router ID

      vlan <vlan-id/vfi-id> - Displays retransmission list information for the specified VLAN / VFI ID.This value ranges from 1 to 65535.

   <vlan –id> - VLAN ID is a unique value that represents the specific VLAN. This value ranges from 1 to 4094.

   <vfi-id> - VFI ID is a VLAN created in the system which contains pseudowires and attachment circuits as member ports. This creates a logical LAN for the VPLS service. This value ranges from 4096 to 65535.

Note:     The VLAN ID 4095 is reserved and may be used to indicate a wildcard match for the VID in management operations or filtering database entries.

Note:     VFI IDs 4096 and 4097 are reserved identifiers used in MPLS PW.

Note:     The theoretical maximum for the maximum number of VFI is 65535 but the actual number of VFI supported is a sizing constant. Based on this, the maximum number of VFI ID accepted in the management interface is restricted. For example if 100 VFIs are supported, the maximum number of VFI supported will be restricted to a hundred added to the maximum number of VLANs. An error message is displayed for any value beyond this range.

      <interface-type> - Displays OSPF for the specified type of interface. The interface can be:

   fastethernet – Officially referred to as 100BASE-T standard. This is a version of LAN standard architecture that supports data transfer upto 100 Megabits per second.

   XL-ethernet – A version of LAN standard architecture that supports data transfer upto 40 Gigabits per second.

   extreme-ethernet – A version of Ethernet that supports data transfer upto 10 Gigabits per second.

   i-lan– Internal LAN created on a bridge per IEEE 802.1ap.

      <interface-id> - Displays OSPF for the specified interface identifier. This is a unique value that represents the specific interface. This value is a combination of slot number and port number separated by a slash, for interface type other than i-lan and port-channel. For example: 0/1 represents that the slot number is 0 and port number is 1. Only i-lan ID is provided, for interface types i-lan. For example: 1 represents i-lan ID.

      <IP-interface-type> - Displays OSPF configuration in the specified L3 pseudowire interface in the system.

      <IP-interface-number> - Displays OSPF configuration for the specified interface identifier. This is a unique value that represents the specific interface. This value ranges from 1 to 65535 for pseudowire interface.

Note:     Maximum number of pseudowire interfaces supported in the system is 100.

OSPFv3

Open Shortest Path First (OSPF) is a link-state, hierarchical Interior Gateway Protocol (IGP) routing algorithm.

OSPFv3 is the modified form of OSPF to support version 6 of the Internet Protocol. The fundamental mechanisms of OSPF (flooding, DR election, area support, SPF calculations, and so on) remain unchanged. However, some changes have been necessary, either due to changes in protocol semantics between IPv4 and IPv6, or simply to handle the increased address size of IPv6.

25.10     area - virtual-link

 

Command Objective

This command sets the Virtual Link between areas.

In OSPFv3, all areas must be connected to a backbone area. If there is a break in backbone continuity, or the backbone is purposefully partitioned, a virtual link can be established. The two endpoints of a virtual link are ABRs. The virtual link must be configured in both routers. The configuration information in each router consists of the other virtual endpoint (the other ABR) and the non-backbone area that the two routers have in common (called the transit area).

If 20.0.0.3 is the Router ID of the neighbor and 100 is the interface index assigned to the OSPFv3 virtual interface, then this interface index is advertised in hello packet sent over the virtual link and in the router's router-LSAs.

Syntax

area <area-id> virtual-link <router-id> <if-index> [hello-interval <seconds>] [retransmit-interval <seconds>] [transmit-delay <seconds>] [dead-interval <seconds>]

      <if-index> - Configures the interface Index assigned to the OSPFv3 virtual interface.This value ranges from 1 to 214783647.

      hello-interval<seconds> - Configures the interval between hello packets on the OSPFv3 virtual link interface. This value ranges from 1 to 65535 seconds.

      retransmit-interval<seconds> - Configures the time between link-state advertisement (LSA) retransmissions for adjacencies belonging to the OSPFv3 virtual link interface. This value ranges from 1 to 1800 seconds.

      transmit-delay<seconds> - Configures the estimated time it takes to transmit a link state update packet over this interface. This value ranges from 1 to 1800 seconds.

      dead-interval<seconds> - Configures the interval at which hello packets must not be seen before its neighbors declare the router down. This value ranges from 1 to 65535 seconds.

RRD

RRD (Route Redistribution) allows different routing protocols to exchange routing information. Using a routing protocol to advertise routes that are learned by other means, such as another routing protocol, static routes, or directly connected routes, is called redistribution. While running a single routing protocol throughout an entire IP internetwork is desirable, multi-protocol routing is widespread for a number of reasons, for example, company mergers, multiple departments managed by multiple network administrators, and multi-vendor environments. If a single routing protocol cannot be used, route redistribution is the only solution. Running different routing protocols is often part of a network design. In any case, having a multiple protocol environment makes redistribution a necessity.

Each routing protocol on a network is separated into an autonomous system (AS). All routers in the same autonomous system (running the same routing protocol) have complete knowledge of the entire AS. A router that connects two (or more) autonomous systems is known as a border router. A border router advertises routing information from one AS to the other AS(s). It is only possible to redistribute routing information for similarly routed protocols. Different routing protocols have different and often incompatible algorithms and metrics.

Route Map

Route Map provides a set of rules which should be satisfied for a route to be redistributed from one routing domain to another. When a route is to be redistributed from a routing domain to another, it is checked against a set of match conditions. If the match conditions are satisfied, access control of Permit/Deny is provided to the route. Route Map permits modification of route information during redistribution. Route Map permits setting conditions using the match clause and setting actions using the set clause.

28.1        route-map

Syntax

route-map <name(1-20)> [{permit | deny }] [ <seqnum(1-10)> ]

no route-map <name (1-20)> [<seqnum (1-10)> ]

Parameter Description

      <name(1-20)> - Configures the route-map name which identifies the route-map in the list of route-maps. This value is a string with maximum length as 20. Route-map name specified will be taken as the configuration mode.

      permit - Sets the access type associated with sequence number in a route-map as Permit. This allows the route entry that matches the match entry rules.

      deny - Sets the access type associated with sequence number in a route-map as Deny. This denies the route entry that matches the match entry rules.

      <seqnum(1-10)> - Configures the route map sequence number which specifies the position of a new route map in the list of route maps already configured with the same name. This value ranges from 1 to 10.
