Usage Guidelines

TheRUCKUS ICX device can function as an IPv6 host, instead of an IPv6 router, if you configure IPv6 addresses on its interfaces but do not enable IPv6 routing using the ipv6 unicast-routing command. From the IPv6 host, you can display information about IPv6 routers to which the host is connected. The host learns about the routers through their router advertisement messages.

If you configure your device to function as an IPv6 router (you configure IPv6 addresses on its interfaces and enable IPv6 routing using the ipv6 unicast-routing command) and then enter theshow ipv6 router command, you will get a message that there are no IPv6 router in the table.

The show ipv6 router command displays the following information:

Output field Description
Router IPv6 address on interface port The IPv6 address for a particular router interface.
Last update The amount of elapsed time (in minutes) between the current and previous updates received from a router.
Hops The default value that should be included in the Hop Count field of the IPv6 header for outgoing IPv6 packets. The hops value applies to the router for which you are displaying information and should be followed by IPv6 hosts attached to the router. A value of 0 indicates that the router leaves this field unspecified.
Lifetime The amount of time (in seconds) that the router is useful as the default router.
Reachable time The amount of time (in milliseconds) that a router assumes a neighbor is reachable after receiving a reachability confirmation. The reachable time value applies to the router for which you are displaying information and should be followed by IPv6 hosts attached to the router. A value of 0 indicates that the router leaves this field unspecified.
Retransmit time The amount of time (in milliseconds) between retransmissions of neighbor solicitation messages. The retransmit time value applies to the router for which you are displaying information and should be followed by IPv6 hosts attached to the router. A value of 0 indicates that the router leaves this field unspecified.
Examples

The following example displays information about the IPv6 routers connected to an IPv6 host.
