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 need to be summarized, because the frequent changes of these
specific routes may lead to route oscillation.
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.
