    Monitoring the Configuration Details for IPv6 Local Address Pools

    Purpose

    Display information on IPv6 local address pools, such as prefix delegation parameters and attributes that control the assignment of prefixes to requesting routers.

    • You can specify the pool name to limit the display to a specific IPv6 local pool.
    • You can specify the statistics keyword to display IPv6 local address pool statistics for prefix delegation.
    • You can use the optional delta keyword with the show ipv6 local pool command to specify that baseline-relative statistics are to be shown. You must use the baseline ipv6 local pool command to set a baseline.

    Note:

    • You must configure an IPv6 license using the license ipv6 command before using the IPv6 routing protocol configuration commands on the E Series router.
    • All IPv6 routing protocol-related configurations are removed from the virtual router when you issue the no ipv6 command.

    Action

    To display information on all IPv6 local address pools:

    host1#show ipv6 local pool
                             IPv6 Local Address Pools
                             ------------------------
