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.

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
