Table 8 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
