This chapter describes the routing commands available in the FASTPATH® CLI.
The commands in this chapter are in one of three functional groups:
- Show commands are used to display switch settings, statistics, and other information.
- Configuration commands are used to configure features and options of the switch. For every configuration command there is a show command that will display the configuration setting.
- Clear commands clear some or all of the settings to factory defaults.
This chapter contains the following sections:
Address Resolution Protocol (ARP) Commands
This section describes the commands you use to configure ARP and to view ARP information on the switch. ARP associates IP addresses with MAC addresses and stores the information as ARP entries in the ARP cache.
arp
This command creates an ARP entry. The value for <ipaddress> is the IP address of a device on a subnet attached to an existing routing interface. <macaddr> is a unicast MAC address for that device.
The format is 6 two-digit hexadecimal numbers that are separated by colons, for example 00:06:29:32:81:40.
Format
|
arp <ipaddress> <macaddr>
|
Mode
|
Global Config
|
no arp
This command deletes an ARP entry. The value for <arpentry> is the IP address of the interface. The value for <ipaddress> is the IP address of a device on a subnet attached to an existing routing interface. <macaddr> is a unicast MAC address for that device.
Format
|
no arp <ipaddress> <macaddr>
|
Mode
|
Global Config
|
ip proxy-arp
This command enables proxy ARP on a router interface. Without proxy ARP, a device only responds to an ARP request if the target IP address is an address configured on the interface where the ARP request arrived. With proxy ARP, the device may also respond if the target IP address is reachable. The device only responds if all next hops in its route to the destination are through interfaces other than the interface that received the ARP request.

ip address
This command configures an IP address on an interface. You can also use this command to configure one or more secondary IP addresses on the interface.The value for <ipaddr> is the IP Address of the interface. The value for <subnetmask> is a 4-digit dotted-decimal number which represents the subnet mask of the interface. The subnet mask must have contiguous ones and be no longer than 30 bits, for example 255.255.255.0. This command changes the label IP address in show ip interface.
Format
|
ip address <ipaddr> <subnetmask> [secondary]

|
Interface Config
|
no ip address
This command deletes an IP address from an interface. The value for <ipaddr> is the IP Address of the interface. The value for <subnetmask> is a 4-digit dotted-decimal number which represents the Subnet Mask of the interface.
Format
|
no ip address <ipaddr> <subnetmask> [secondary]
|
Mode
|
Interface Config
|
ip route
This command configures a static route.
- The <ipaddr> parameter is a valid IP address, and <subnetmask> is a valid subnet mask.
- The <nexthopip> parameter is a valid IP address of the next hop router.
- The optional <preference> parameter is an integer (value from 1 to 255) that allows you to specify the preference value (sometimes called “administrative distance”) of an individual static route.
Among routes to the same destination, the route with the lowest preference value is the route entered into the forwarding database. By specifying the preference of a static route, you control whether a static route is more or less preferred than routes from dynamic routing protocols. The preference also controls whether a static route is more or less preferred than other static routes to the same destination. A route with a preference of 255 cannot be used to forward traffic.
For the static routes to be visible, you must perform the following steps:
- Enable ip routing globally.
- Enable ip routing for the interface.
- Confirm that the associated link is also up.
Default
|
preference--1
|
Format
|
ip route <ipaddr> <subnetmask> <nexthopip> [<preference>]
|
Mode
|
Global Config
|
no ip route
This command deletes all next hops to a destination static route. If you use the <nexthopip> parameter, the next hop is deleted. If you use the <preference> value, the preference value of the static route is reset to its default.
Format

no ip route <ipaddr> <subnetmask> [{<nexthopip> | <preference>}]

ip route default
This command configures the default route. The value for <nexthopip> is a valid IP address of the next hop router. The <preference> is an integer value from 1 to 255. A route with a preference of 255 cannot be used to forward traffic.
Default
|
preference--1
|
Format
|
ip route default <nexthopip> [<preference>]
|
Mode
|
Global Config
|
no ip route default
This command deletes all configured default routes. If the optional <nexthopip> parameter is designated, the specific next hop is deleted from the configured default route and if the optional preference value is designated, the preference of the configured default route is reset to its default.

no ip route default [{<nexthopip> | <preference>}]

Global Config
|
ip route distance
This command sets the default distance (preference) for static routes. Lower route distance values are preferred when determining the best route. The ip route and ip route default commands allow you to optionally set the distance (preference) of an individual static route. The default distance is used when no distance is specified in these commands. Changing the default distance does not update the distance of existing static routes, even if they were assigned the original default distance. The new default distance will only be applied to static routes created after invoking the ip route distance command.
Default
|
1

ip mtu
This command sets the IP Maximum Transmission Unit (MTU) on a routing interface. The IP MTU is the size of the largest IP packet that can be transmitted on the interface without fragmentation. FASTPATH software currently does not fragment IP packets.
- Packets forwarded in hardware ignore the IP MTU.
- Packets forwarded in software are dropped if they exceed the IP MTU of the outgoing interface.
Packets originated on the router, such as OSPF packets, may be fragmented by the IP stack. The IP stack uses its default IP MTU and ignores the value set using the ip mtu command.
OSPF advertises the IP MTU in the Database Description packets it sends to its neighbors during database exchange. If two OSPF neighbors advertise different IP MTUs, they will not form an adjacency (unless OSPF has been instructed to ignore differences in IP MTU with the ip ospf mtu-ignore command.)
Note - The IP MTU size refers to the maximum size of the IP packet (IP Header + IP payload). It does not include any extra bytes that may be required for Layer-2 headers. To receive and process packets, the Ethernet MTU (mtu) must take into account the size of the Ethernet header.
|
Default
|
1500 bytes

VRRP Tracking Commands
This section describes the commands for tracking VRRP. The configuration of VRRP tracking is accomplished with two logical steps:
1. Configure the events that can impact VRRP priority change by defining tracking objects.
2. Link between VRRP priority changes and tracking objects by specifying VRRP priority change for state change in the tracked objects.
A track command object can track an interface property or IP layer properties. An interface might be tracked by its line-protocol state (up/down) or by its IP routing state (enable/disable). Use the commands in this section according to the preferred tracking method.
track interface line-protocol
This command tracks the link state of an interface. The object will be up when the interface is linked.
Default
|

- IP routing is enabled and active on the interface
- Interface line-protocol state is up
- Interface IP address is known (The IP address is configured or received through the Dynamic Host Configuration Protocol (DHCP) or IP Control Protocol (IPCP) negotiation.)
An IP-routing object is considered down when one of the following criteria exist:
- IP routing is disabled globally
- Interface line-protocol state is down
- Interface IP address is unknown (The IP address is not configured or received through DHCP or IPCP negotiation.)

distance ospf (OSPF)
This command sets the route preference value of OSPF in the router. Lower route preference values are preferred when determining the best route. The type of OSPF can be intra, inter, type-1, or type-2. The OSPF specification (RFC 2328) requires that preferences must be given to the routes learned via OSPF in the following order: intra < inter < type-1 < type-2. The <preference> range is 1 to 255. A route with a preference of 255 cannot be used to forward traffic.
Default
