    Monitoring Active IPv6 Protocols


    Display detailed information about IPv6 protocols currently configured on the router.


    • 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.


    To display detailed information about IPv6 protocols currently configured on the router:

    host1#show ipv6 protocols
    Routing Protocol is “ bgp 100"
      Local router ID, local AS 100
      Administrative state is Start
      Operational state is Up
      Shutdown in overload state is disabled
      Default local preference is 100
      IGP synchronization is enabled
      Default originate is disabled
      Auto summary is enabled
      Always compare MED is disabled
      Compare MED within confederation is disabled
      Advertise inactive routes is disabled
      Advertise best external route to internal peers is disabled
      Enforce first AS is disabled
      Missing MED as worst is disabled
      Route flap dampening is disabled
      Log neighbor changes is disabled
      Fast External Fallover is disabled
      No maximum received AS-path length
      BGP administrative distances are 20 (ext), 200 (int), and 200 (local)
      Client-to-client reflection is enabled
      Cluster ID is
      Route-target filter is enabled
      Default IPv4-unicast is enabled
      Local-RIB version 8. FIB version 8.
        No neighbors are configured
      Routing for Networks:
      Aggregate Generation for Unicast Routes:

    To display only a list of currently configured protocols:

    host1#show ipv6 protocols summary
    bgp 100


    Table 1 lists the show ipv6 protocols command output fields.
