Notes

The command output does not include routes that are excluded by learned route filtering or do not have priority under BGP4+.

To include detailed information about route attributes in the command output, use the show ipv6 bgp operation command with the received-routes and -F parameters specified. Use this method to check the ORIGIN, AS_PATH, MED, LOCAL_PREF, and COMMUNITIES attributes of the routes.
