Description

Associate Border Gateway Protocol (BGP) autonomous system (AS) path information with a static, aggregate, or generated route.

Options

aggregator—(Optional) Attach the BGP aggregator path attribute to the aggregate route. You must specify the last AS number that formed the aggregate route (encoded as two octets) for as-number, followed by the IP address of the BGP system that formed the aggregate route for in-address.

as-path—(Optional) AS path to include with the route. It can include a combination of individual AS path numbers and AS sets. Enclose sets in brackets ( [ ] ). The first AS number in the path represents the AS immediately adjacent to the local AS. Each subsequent number represents an AS that is progressively farther from the local AS, heading toward the origin of the path. You cannot specify a regular expression for as-path; you must use a full, valid AS path.

atomic-aggregate—(Optional) Attach the BGP atomic-aggregate path attribute to the aggregate route. This path attribute indicates that the local system selected a less specific route instead of a more specific route.

origin egp—BGP origin attribute that indicates that the path information originated in another AS.

origin igp—BGP origin attribute that indicates that the path information originated within the local AS.

origin incomplete—BGP origin attribute that indicates that the path information was learned by some other means.
