Table 187 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.
