30.3.2 Checking routes resulting from SPF calculations on OSPFv3 [SL-L3A]

If a filter invalidates an external AS route computed by the SPF algorithm of the OSPFv3 protocol, the route is still entered into the routing table but as an invalid route. You can check the external AS routes that the OSPFv3 protocol has generated, including invalid routes, by executing the show ipv6 route operation command with the all-routes and -T ospf external parameters specified.
