as-set
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.
detail-suppressed
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.
