Parameters

<ADDRESS/MASK>: Specifies an aggregate address and mask. Format: A.B.C.D/M
as-set: Select to create an aggregate entry using the same rules that the command follows without this keyword, but the AS_PATH attribute advertised for this route will contain an AS_SET consisting of all AS numbers contained in all paths that are being summarized.
summary-only: Select to create the aggregate route but also suppresses the advertisements of more-specific routes to all neighbors.
suppress-map <MAP-NAME>: Specifies an aggregate route for creation, but suppresses the advertisement of the created route. Match clauses of route maps can be used to suppress some more-specific routes of the aggregate selectively, and leave others unsuppressed. IP prefix lists and as_path lists match clauses are supported.
advertise-map <MAP-NAME>: Specifies routes that will be used to build different attributes of the aggregate route, such as AS_SET or community.
attribute-map <MAP-NAME>: Specifies that the attributes of the aggregate route can be changed.
