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

  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
