1100 BigIron RX Series Configuration Guide53-1001810-01Displaying global IPv6 information43From 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. To displayinformation about the IPv6 routers connected to an IPv6 host, enter the following command at anyCLI level.Syntax: show ipv6 routerIf you configure your Brocade device to function as an IPv6 router (you configure IPv6 addresses onits interfaces and enable IPv6 routing using the ipv6 unicast-routing command) and you enter theshow ipv6 router command, you will receive the following output.Meaningful output for this command is generated for Brocade devices configured to function asIPv6 hosts only.This display shows the following information.Displaying IPv6 TCP informationYou can display the following IPv6 TCP information:• General information about each TCP connection on the router, including the percentage of freememory for each of the internal TCP buffers.• Detailed information about a specified TCP connection.TABLE 173 IPv6 local router information fieldsThis field... Displays...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 andprevious updates received from a router.Hops The default value that should be included in the Hop Count field of theIPv6 header for outgoing IPv6 packets. The hops value applies to therouter for which you are displaying information and should be followedby IPv6 hosts attached to the router. A value of 0 indicates that therouter leaves this field unspecified.Lifetime The amount of time (in seconds) that the router is useful as the defaultrouter.Reachable time The amount of time (in milliseconds) that a router assumes a neighbor isreachable after receiving a reachability confirmation. The reachabletime value applies to the router for which you are displaying informationand should be followed by IPv6 hosts attached to the router. A value of 0indicates that the router leaves this field unspecified.Retransmit time The amount of time (in milliseconds) between retransmissions ofneighbor solicitation messages. The retransmit time value applies to therouter for which you are displaying information and should be followedby IPv6 hosts attached to the router. A value of 0 indicates that therouter leaves this field unspecified.BigIron RX# show ipv6 routerRouter fe80::2e0:80ff:fe46:3431 on Ethernet 50, last update 0 minHops 64, Lifetime 1800 secReachable time 0 msec, Retransmit time 0 msecNo IPv6 router in table
