show bgp ipv6 unicast summary 

When the router configuration is modified so that changes can be made to the IPv6 configuration, then the router does not return a result for this command. As a result, any information pertaining to IPv6 configuration change cannot be obtained.

  • If the configuration change affects the status of the connection and the CLI response can be retrieved, then the status of the Cisco IPv6 BGP configuration can updated.

  • If the configuration change does not return any response to the CLI command, then the BGP session will be shown as disconnected (with either BGPSesssion::Down or BGPService::Down as appropriate) and no further processing of notifications take place.
