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 need to be summarized, because the frequent changes of these
specific routes may 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.
Used to create a summary route and suppress the advertisement of some
summarized routes. If you want to suppress some routes selectively and
leave other routes still advertised, use the if-match clause of the
route-policy command.
Selects only routes satisfying the route policy for route summarization
Sets attributes except the AS-PATH attribute for the summary route. The
same work can be done by using the peer route-policy command.
