Tabl e 93 Keywords function
Keyword Function
as-set By setting this keyword, you can create an aggregated route whose AS
path contains the information of all the aggregation routes. This keyword
is not recommended when aggregating many AS paths because frequent
changes of the specific route may result in routing oscillation.

d
This keyword suppresses advertisement of all the specific routes, but not of
the aggregated routes. Using the peer filter-policy command, you can
suppress some specific routes.

advertising of the specified routes. Using the if-match clause in the
route-policy command, you can choose to suppress advertisement of
some specific routes.
origin-policy Using this command, you can only choose the specific routes matching the
Route-policy to create aggregated route.
attribute-policy Using this keyword, you can set the attributes of the aggregation route.
The peer route-policy command can also enables you to complete the
same setting.
