Table 4-1 The use of the keywords
keywords use
as-set
Used to produce an aggregated route whose AS path
information includes detailed routes. Use this keyword
carefully when many AS paths need to be aggregated, for the
frequent change of routes may lead to route vibration.
detail-suppressed
This keyword does not establish any aggregated route, but it
restrains the advertisement of all the specific routes. If only
some specific routes are to be restrained, use the peer
filter-policy command carefully.
suppress-policy
Create an aggregated route with this keyword, at the same
time, the advertisement of the specified route is restrained. If
you want to restrain some specific routes selectively and
leaves other routes still being advertised, use the if-match
sub-statement of the route-policy command.
origin-policy
select only the specific routes that are in accordance with
route-policy to create an aggregated route.
attribute-policy
set aggregated route attributes. The same work can be done
by using peer route-policy, etc.
