Table 77 Functions of the keywords

words 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.
