By default, there is no route aggregation.
The keywords are explained as follows:
Table 69 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-suppresse This keyword does not suppress any aggregated route, but it restrains the
d 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.
