Configuring manual route summarization
By configuring manual route summarization, you can summarize both redistributed routes and
routes injected using the network command and determine the mask length for a summary route as
needed.
The output interface of a BGP summary route is Null 0. With route summarization, BGP advertises
fewer routes to its peers. A summary route must not be optimal; otherwise, BGP will fail to forward
the packets matching the route. If a summarized specific route has the same mask as the summary
route but has a lower priority, the summary route becomes the optimal route. In this case, you must
change the priority of the summary or the specific route to make the specific route the optimal route.
