Command Reference
Description The keywords are explained as follows:
Table 1 Functions of the keywords
Keywords Function
as-set Used to create an aggregated route, whose AS path information
includes individual routes. Use this keyword carefully when many AS
paths need to be aggregated, for the frequent change of individual
routes may lead to route vibration.
detail-suppressed This keyword does not suppress any aggregated route, but it
suppresses the advertisement of all the individual routes. If only some
individual routes are to be suppressed, use the peer
filter-policy command.
suppress-policy Used to create an aggregated route and suppress the advertisement of
the specified route. If you want to suppress some specific routes
selectively and leave other routes still being advertised, use the
if-match clause of the route-policy command.
origin-policy Selects only the individual 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.
