Creating a Route Map
When a route map is created, it is given a name (up to 20 characters), a sequence number, and an action
(permit or deny). Specifying a sequence number is optional. If a value is not configured, then the number
50 is used by default.
(permit or deny). Specifying a sequence number is optional. If a value is not configured, then the number
50 is used by default.
To create a route map, use the ip route-map command with the action parameter. For example,
-> ip route-map ospf-to-rip sequence-number 10 action permit
The above command creates the ospf-to-rip route map, assigns a sequence number of 10 to the route
map, and specifies a permit action.
map, and specifies a permit action.
To optionally filter routes before redistribution, use the ip route-map command with a match parameter
to configure match criteria for incoming routes. For example,
to configure match criteria for incoming routes. For example,
-> ip route-map ospf-to-rip sequence-number 10 match tag 8
The above command configures a match statement for the ospf-to-rip route map to filter routes based on
their tag value. When this route map is applied, only OSPF routes with a tag value of eight are redistrib-
uted into the RIP network. All other routes with a different tag value are dropped.

uted into the RIP network. All other routes with a different tag value are dropped.
Note. Configuring match statements is not required. However, if a route map does not contain any match
statements and the route map is applied using the

To modify route information before it is redistributed, use the ip route-map command with a set parame-
ter. For example,
ter. For example,
-> ip route-map ospf-to-rip sequence-number 10 set tag 5
The above command configures a set statement for the ospf-to-rip route map that changes the route tag
value to five. Because this statement is part of the ospf-to-rip route map, it is only applied to routes that
have an existing tag value equal to eight.
value to five. Because this statement is part of the ospf-to-rip route map, it is only applied to routes that
have an existing tag value equal to eight.
The following is a summary of the commands used in the above examples:
-> ip route-map ospf-to-rip sequence-number 10 action permit
-> ip route-map ospf-to-rip sequence-number 10 match tag 8
-> ip route-map ospf-to-rip sequence-number 10 set tag 5
To verify a route map configuration, use the
