Chapter 38 Configuring IP Unicast Routing

Configuring Protocol-Independent Features

Note Although each of Steps 3 through 14 in the following section is optional, you must enter at least one match route-map configuration command and one set route-map configuration command.

Beginning in privileged EXEC mode, follow these steps to configure a route map for redistribution:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	route-map map-tag[permit deny] [sequence number]	Define any route maps used to control redistribution and
		enter route-map configuration mode.
		map-tag—A meaningful name for the route map. The
		redistribute router configuration command uses this
		name to reference this route map. Multiple route maps
		might share the same map tag name.
		(Optional) If permit is specified and the match criteria
		are met for this route map, the route is redistributed as
		controlled by the set actions. If deny is specified, the
		route is not redistributed.
		sequence number (Optional)— Number that indicates the
		position a new route map is to have in the list of route
		maps already configured with the same name.
Step 3
	match as-pathpath-list-number	Match a BGP AS path access list.
Step 4
	match community-list community-list-number[exact]	Match a BGP community list.
Step 5
	match ip address {access-list-number	Match a standard access list by specifying the name or
	access-list-name}[...access-list-number	number. It can be an integer from 1 to 199.
	...access-list-name]
Step 6
	match metric metric-value	Match the specified route metric. The metric-value can be
		an EIGRP metric with a specified value from 0
		to 4294967295.
Step 7
	match ip next-hop{access-list-number	Match a next-hop router address passed by one of the
	access-list-name}[...access-list-number	access lists specified (numbered from 1 to 199).
	...access-list-name]
Step 8
	match tag tag value [...tag-value]	Match the specified tag value in a list of one or more route
		tag values. Each can be an integer from 0 to 4294967295.
Step 9
	match interface type number [...type number]	Match the specified next hop route out one of the
		specified interfaces.
Step 10
	match ip route-source {access-list-number	Match the address specified by the specified advertised
	access-list-name}[...access-list-number	access lists.
	...access-list-name]
Step 11
	match route-type {local internal external [type-1	Match the specified route-type:
	type-2]}	• local—Locally generated BGP routes.
		• internal—OSPF intra-area and interarea routes or
		EIGRP internal routes.
		• external—OSPF external routes (Type 1 or Type 2)
		or EIGRP external routes.
