Command context

config-bgp-ipv4-uc

config-bgp-ipv6-uc

Parameters

<ADDRESS>

Specifies an aggregate address in IPv4 format (x.x.x.x), where x is a decimal number from 0 to 255, or IPv6 format (xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx), where x is a hexadecimal number from 0 to F.

<MASK>

Specifies the number of bits in the address mask in CIDR format (x), where x is a decimal number from 0 to 128.

as-set

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

Creates the aggregate route but also suppresses 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.

Authority

Administrators or local user group members with execution rights for this command.
