The use of the keywords
Keyword
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 suppress 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
Selects only the specific routes that are in accordance with
route-policy to create an aggregated route.
attribute-policy
Sets aggregated route attributes. The same work can be
done by using the
peer route-policy
command, etc.
