IPv6 Commands |
This chapter describes the IPv6 commands available in the FASTPATH® CLI.
The commands in this chapter are in one of three functional groups:
This chapter contains the following sections:
The commands in this section describe how to create, delete, and manage tunnel interfaces.Several different types of tunnels provide functionality to facilitate the transition of IPv4 networks to IPv6 networks. These tunnels are divided into two classes: configured and automatic. The distinction is that configured tunnels are explicitly configured with a destination or endpoint of the tunnel. Automatic tunnels, in contrast, infer the endpoint of the tunnel from the destination address of packets routed into the tunnel. To assign an IP address to the tunnel interface, see ip address. To assign an IPv6 address to the tunnel interface, see ipv6 address.
Use this command to enter the Interface Config mode for a tunnel interface. The <tunnel-id> range is 0 to 7.
This command removes the tunnel interface and associated configuration parameters for the specified tunnel interface.
This command specifies the source transport address of the tunnel, either explicitly or by reference to an interface.
This command specifies the destination transport address of the tunnel.
This command specifies the mode of the tunnel.
This command displays the parameters related to tunnel such as tunnel mode, tunnel source address and tunnel destination address.
If you do not specify a tunnel ID, the command shows the following information for each configured tunnel.
The commands in this section describe how to create, delete, and manage loopback interfaces. A loopback interface is always expected to be up. This interface can provide the source address for sent packets and can receive both local and remote packets. The loopback interface is typically used by routing protocols.
To assign an IP address to the loopback interface, see ip address. To assign an IPv6 address to the loopback interface, see ipv6 address.
Use this command to enter the Interface Config mode for a loopback interface. The range of the loopback ID is 0 to 7.
This command removes the loopback interface and associated configuration parameters for the specified loopback interface.
This command displays information about configured loopback interfaces.
If you do not specify a loopback ID, the following information appears for each loopback interface on the system.
This section describes the IPv6 commands you use to configure IPv6 on the system and on the interfaces. This section also describes IPv6 management commands and show commands.
This command enables IPv6 forwarding on the router
This command disables ipv6 forwarding on the router.
Use this command to enable the forwarding of IPv6 unicast datagrams.
Use this command to disable the forwarding of IPv6 unicast datagrams.
Use this command to enable IPv6 routing on an interface, including tunnel and loopback interfaces, that has not been configured with an explicit IPv6 address. When you use this command, the interface is automatically configured with a link-local address. You do not need to use this command if you configured an IPv6 global address on the interface.
Use this command to disable IPv6 routing on an interface.
Use this command to configure an IPv6 address on an interface, including tunnel and loopback interfaces, and to enable IPv6 processing on this interface. You can assign multiple globally reachable addresses to an interface by using this command. You do not need to assign a link-local address by using this command since one is automatically created. The <prefix> field consists of the bits of the address to be configured. The <prefix_length> designates how many of the high-order contiguous bits of the address make up the prefix.
You can express IPv6 addresses in eight blocks. Also of note is that instead of a period, a colon now separates each block. For simplification, leading zeros of each 16 bit block can be omitted. One sequence of 16 bit blocks containing only zeros can be replaced with a double colon "::", but not more than one at a time (otherwise it is no longer a unique representation).
The hexadecimal letters in the IPv6 addresses are not case-sensitive. An example of an IPv6 prefix and prefix length is 3ffe:1::1234/64.
The optional [eui-64] field designates that IPv6 processing on the interfaces was enabled using an EUI-64 interface ID in the low order 64 bits of the address. If you use this option, the value of <prefix_length> must be 64 bits.
Use this command to remove all IPv6 addresses on an interface or specified IPv6 address. The <prefix> parameter consists of the bits of the address to be configured. The <prefix_length> designates how many of the high-order contiguous bits of the address comprise the prefix.The optional [eui-64] field designates that IPv6 processing on the interfaces was enabled using an EUI-64 interface ID in the low order 64 bits of the address.
If you do not supply any parameters, the command deletes all the IPv6 addresses on an interface.
Use this command to configure an IPv6 static route. The <ipv6-prefix> is the IPv6 network that is the destination of the static route. The <prefix_length> is the length of the IPv6 prefix -- a decimal value (usually 0-64) that shows how many of the high-order contiguous bits of the address comprise the prefix (the network portion of the address). A slash mark must precede the <prefix_length>. The <next-hop-address> is the IPv6 address of the next hop that can be used to reach the specified network. The <preference> parameter is a value the router uses to compare this route with routes from other route sources that have the same destination. The range for <preference> is 1 - 255, and the default value is 1. The interface <slot/port> identifies direct static routes from point-to-point and broadcast interfaces, and must be specified when using a link-local address as the next hop. A route with a preference of 255 cannot be used to forward traffic.
ipv6 route <ipv6-prefix>/<prefix_length> {<next-hop-address> [<preference>] | interface <slot/port> <next-hop-address> [<preference>]} |
|
Use this command to delete an IPv6 static route. Use the command without the optional parameters to delete all static routes to the specified destination. Use the <preference> parameter to revert preference of a route to default preference.
no ipv6 route <ipv6-prefix>/<prefix_length> [{<next-hop-address> | interface <slot/port> <next-hop-address> | <preference>}] |
|
This command sets the maximum transmission unit (MTU) size, in bytes, of IPv6 packets on an interface. This command replaces the default or link MTU with a new MTU value.
Note - The default MTU value for a tunnel interface is 1480. You cannot change this value. |
This command resets maximum transmission unit value to default value.
This command sets the number of duplicate address detection probes transmitted. Duplicate address detection verifies that an IPv6 address on an interface is unique.
This command resets to number of duplicate address detection value to default value.
This command sets the “managed address configuration” flag in router advertisements. When the value is true, end nodes use DHCPv6. When the value is false, end nodes automatically configure addresses.
This command resets the “managed address configuration” flag in router advertisements to the default value.
This command sets the interval between router advertisements for advertised neighbor solicitations, in milliseconds. An advertised value of 0 means the interval is unspecified.
This command resets the neighbor solicit retransmission interval of the specified interface to the default value.
This command sets the “other stateful configuration” flag in router advertisements sent from the interface.
This command resets the “other stateful configuration” flag back to its default value in router advertisements sent from the interface.
This command sets the transmission interval between router advertisements.
This command sets router advertisement interval to the default.
This command sets the value, in seconds, that is placed in the Router Lifetime field of the router advertisements sent from the interface. The <lifetime> value must be zero, or it must be an integer between the value of the router advertisement transmission interval and 9000. A value of zero means this router is not to be used as the default router.
This command resets router lifetime to the default value.
This command sets the router advertisement time to consider a neighbor reachable after neighbor discovery confirmation. Reachable time is specified in milliseconds. A value of zero means the time is unspecified by the router.
This command means reachable time is unspecified for the router.
This command suppresses router advertisement transmission on an interface.
This command enables router transmission on an interface
This command sets the IPv6 prefixes to include in the router advertisement. The first optional parameter is the valid lifetime of the router, in seconds. You can specify a value or indicate that the lifetime value is infinite. The second optional parameter is the preferred lifetime of the router.
Use this command to determine whether another computer is on the network. To use the command, configure the switch for network (in-band) connection. The source and target devices must have the ping utility enabled and running on top of TCP/IP. The switch can be pinged from any IP workstation with which the switch is connected through the default VLAN (VLAN 1), as long as there is a physical path between the switch and the workstation. The terminal interface sends three pings to the target station. Use the <ipv6-address> parameter to ping an interface by using the global IPv6 address of the interface. Use the optional size keyword to specify the size of the ping packet.

This section describes the commands you use to configure OSPFv3, which is a link-state routing protocol that you use to route traffic within a network.
This command enables OSPF on a router interface or loopback interface.
This command disables OSPF on a router interface or loopback interface.
This command sets the OSPF area to which the specified router interface belongs. The <areaid> is an IPv6 address, formatted as a 4-digit dotted-decimal number or a decimal value in the range of <0-4294967295>. The <areaid> uniquely identifies the area to which the interface connects. Assigning an area id, which does not exist on an interface, causes the area to be created with default values.
This command configures the cost on an OSPF interface. The <cost> parameter has a range of 1 to 65535.
This command configures the default cost on an OSPF interface.
This command sets the OSPF dead interval for the specified interface. The value for <seconds> is a valid positive integer, which represents the length of time in seconds that a router's Hello packets have not been seen before its neighbor routers declare that the router is down. The value for the length of time must be the same for all routers attached to a common network. This value should be some multiple of the Hello Interval (i.e. 4). Valid values range for <seconds> is from 1 to 2147483647.
This command sets the default OSPF dead interval for the specified interface.
This command sets the OSPF hello interval for the specified interface. The value for <seconds> is a valid positive integer, which represents the length of time in seconds. The value for the length of time must be the same for all routers attached to a network.
Valid values for <seconds> range from 1 to 65535.
This command sets the default OSPF hello interval for the specified interface.
This command disables OSPF maximum transmission unit (MTU) mismatch detection. OSPF Database Description packets specify the size of the largest IP packet that can be sent without fragmentation on the interface. When a router receives a Database Description packet, it examines the MTU advertised by the neighbor. By default, if the MTU is larger than the router can accept, the Database Description packet is rejected and the OSPF adjacency is not established.
This command enables the OSPF MTU mismatch detection.
This command changes the default OSPF network type for the interface. Normally, the network type is determined from the physical IP network type. By default all Ethernet networks are OSPF type broadcast. Similarly, tunnel interfaces default to point-to-point. When an Ethernet port is used as a single large bandwidth IP network between two routers, the network type can be point-to-point since there are only two routers. Using point-to-point as the network type eliminates the overhead of the OSPF designated router election. It is normally not useful to set a tunnel to OSPF network type broadcast.
This command sets the interface type to the default value.
This command sets the OSPF priority for the specified router interface. The priority of the interface is a priority integer from 0 to 255. A value of 0 indicates that the router is not eligible to become the designated router on this network.
This command sets the default OSPF priority for the specified router interface.
This command sets the OSPF retransmit Interval for the specified interface. The retransmit interval is specified in seconds. The value for <seconds> is the number of seconds between link-state advertisement retransmissions for adjacencies belonging to this router interface. This value is also used when retransmitting database description and link-state request packets. Valid values range from 0 to 3600 (1 hour).
This command sets the default OSPF retransmit Interval for the specified interface.
This command sets the OSPF Transit Delay for the specified interface. The transmit delay is specified in seconds. In addition, it sets the estimated number of seconds it takes to transmit a link state update packet over this interface. Valid values for <seconds> range from 1 to 3600 (1 hour).
This command sets the default OSPF Transit Delay for the specified interface.
Use this command to enter Router OSPFv3 Config mode.
This command configures the monetary default cost for the stub area. The operator must specify the area id and an integer value between 1-16777215.
This command configures the specified areaid to function as an NSSA.
This command disables nssa from the specified area id.
This command configures the metric value and type for the default route advertised into the NSSA. The optional metric parameter specifies the metric of the default route and is to be in a range of 1-16777214. If no metric is specified, the default value is 10. The metric type can be comparable (nssa-external 1) or non-comparable (nssa-external 2).
area <areaid> nssa default-info-originate [<metric>] [{comparable | non-comparable}] |
|
---|---|
This command configures the NSSA ABR so that learned external routes will not be redistributed to the NSSA.
This command configures the NSSA so that summary LSAs are not advertised into the NSSA.
This command configures the translator role of the NSSA. A value of always causes the router to assume the role of the translator the instant it becomes a border router and a value of candidate causes the router to participate in the translator election process when it attains border router status.
This command configures the translator <stabilityinterval> of the NSSA. The <stabilityinterval> is the period of time that an elected translator continues to perform its duties after it determines that its translator status has been deposed by another router.
This command creates a specified area range for a specified NSSA. The <ipaddr> is a valid IP address. The <subnetmask> is a valid subnet mask. The LSDB type must be specified by either summarylink or nssaexternallink, and the advertising of the area range can be allowed or suppressed.
area <areaid> range <ipv6-prefix> <prefix-length> {summarylink | nssaexternallink} [advertise | not-advertise] |
|
---|---|
This command deletes a specified area range. The <ipaddr> is a valid IP address. The <subnetmask> is a valid subnet mask.
This command creates a stub area for the specified area ID. A stub area is characterized by the fact that AS External LSAs are not propagated into the area. Removing AS External LSAs and Summary LSAs can significantly reduce the link state database of routers within the stub area.

This command is used to set a default for the metric of distributed routes.
This command is used to set a default for the metric of distributed routes.
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 route 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.
This command sets the default route preference value of OSPF in the router. The type of OSPF route can be intra, inter, type-1, or type-2.
This command resets the default administrative mode of OSPF in the router (active).
This command sets the administrative mode of OSPF in the router to inactive.
This command configures the exit overflow interval for OSPF. It describes the number of seconds after entering Overflow state that a router will wait before attempting to leave the Overflow State. This allows the router to again originate non-default AS-external-LSAs. When set to 0, the router will not leave Overflow State until restarted. The range for <seconds> is 0 to 2147483647 seconds.
This command configures the default exit overflow interval for OSPF.
This command configures the external LSDB limit for OSPF. If the value is -1, then there is no limit. When the number of non-default AS-external-LSAs in a router's link-state database reaches the external LSDB limit, the router enters overflow state. The router never holds more than the external LSDB limit non-default AS-external-LSAs in it database. The external LSDB limit MUST be set identically in all routers attached to the OSPF backbone and/or any regular OSPF area. The range for <limit> is -1 to 2147483647.

The relay server may in turn use this information in determining an address to assign to a DHCPv6 client.
Use this command to configure a number to represent the DHCPv6 the “remote-id” sub-option.
Use this command from Global Config mode to enter IPv6 DHCP Pool Config mode. Use the exit command to return to Global Config mode. To return to the User EXEC mode, enter CTRL+Z. The <pool-name> should be less than 31 alpha-numeric characters. DHCPv6 pools are used to specify information for DHCPv6 server to distribute to DHCPv6 clients. These pools are shared between multiple interfaces over which DHCPv6 server capabilities are configured.
This command removes the specified DHCPv6 pool.
This command sets the DNS domain name which is provided to DHCPv6 client by DHCPv6 server. DNS domain name is configured for stateless server support. Domain name consist of no more than 31 alpha-numeric characters. DHCPv6 pool can have multiple number of domain names with maximum of 8.
This command will remove dhcpv6 domain name from dhcpv6 pool.
