Policy-based Routing for BGP

If the match criteria are not met, and the permit keyword specified, the

next route map with the same map-name is tested. If a route passes

none of the match criteria for the set of route maps sharing the same

name, it is not policy routed by that set.

If the match criteria are met for the route map and the deny keyword

specified, the packet is not policy routed, and no further route maps

sharing the same map-name are examined. If the packet is not policy

routed, the normal forwarding process is used.

Processing for exceptions include the following results:

For a deny route-map, if it does not have a match clause, any

routing message is matched, and therefore all routes are denied.

For a deny route-map which includes a match clause for an access-

list, if the access-list does not exist, no routing message will be

matched, and therefore all routes are skipped.

For a permit route-map, if it does not have a match clause, any

routing message is matched, and therefore all routes are permitted.

For a permit route-map which includes a match clause for an

access-list, if the access-list does not exist, no routing messages

are matched, and therefore all routes are skipped.

Console(config)#route-map r1 permit 1

Console(config-route-map)#match as-path 60

Console(config-route-map)#set weight 30

Console(config-route-map)#

This command jumps to another route map after match and set commands

are executed. Use the no form to remove an entry from a route map.

call map-name

map-name – Name for the route map. (Range: 1-128 case-sensitive

alphanumeric characters)

Only one call clause is permitted per route map. The call clause executed

only after all match and set commands are executed.
