Function
Used to create a summary route, whose AS path contains the AS path
information of summarized routes. Use this keyword carefully when
many AS paths must be summarized, because the frequent changes of
these specific routes might lead to route flaps.
This keyword does not suppress the summary route, but it suppresses
the advertisement of all the more specific routes. To summarize only
some specific routes, use the peer filter-policy command.
