Table 74
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 must be summarized, because the frequent changes to these
specific routes might lead to route oscillation.
detail-suppressed
Does not suppress the summary route, but suppresses the advertisement of
all the more specific routes. To summarize only some specific routes, use the
peer filter-policy
command.
suppress-policy
Used to create a summary route and suppress the advertisement of some
summarized routes. To suppress some routes selectively and leave other
routes advertised, use the
if-match
clause of the
route-policy
command.
origin-policy
Selects only the routes that satisfy the routing policy for route
summarization.
