Table 28 Functions of the keywords
Keywords Function
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.
