config-bgp-ipv6-uc

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 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.
