This command sets the originating protocol to match in routing messages.
Use the no form to remove this entry from a route map.

match origin {egp | igp | incomplete}
no match origin
egp – Routes learned from exterior gateway protocols.
igp – Routes learned from internal gateway protocols.
incomplete – Routes of uncertain origin.

XAMPLE
Console(config)#route-map RD permit 8
Console(config-route-map)#match origin igp
Console(config-route-map)#set weight 30
Console(config-route-map)#
This command sets the maximum AS path length allowed for propagation
of more specific prefixes to match in routing messages. Use the no form to
remove this entry from a route map.

◆ To perform inter-domain traffic engineering, a multi-homed site can
advertise its prefix to all of its neighbors via an aggregate address, and
also advertise more specific prefixes to a subset of its neighbors. The
longest match lookup algorithm then causes traffic for the more specific
prefixes to be forwarded to the subset of neighbors with the more
specific prefix.
