19.11 match origin

Use this command to match origin code.

Use the no parameter with this command to disable this matching.

The origin attribute defines the origin of the path information. The egp parameter is indicated as

an e in the routing table, and it indicates that the origin of the information is learned via Exterior

Gateway Protocol. The igp parameter is indicated as an i in the routing table, and it indicates

the origin of the path information is interior to the originating AS.

The incomplete parameter is indicated as a ? in the routing table, and indicates that the origin of

the path information is unknown or learned through other means. If a static route is redistributed

into BGP, the origin of the route is incomplete.

The match origin command specifies the origin to be matched. If there is a match for the

specified origin, and permit is specified, the route is redistributed or controlled as specified by

the set action. If the match criteria are met, and deny is specified, the route is not redistributed

or controlled. If the match criteria are not met, the route is neither accepted nor forwarded,

irrespective of permit or deny specifications.

The route specified by the policies might not be the same as specified by the routing protocols.

Setting policies enable packets to take different routes depending on their length or content.

Packet forwarding based on configured policies overrides packet forwarding specified in routing

tables.

Note:

This command is valid for BGP only.
