• Prepend AS numbers to the front of the route AS-path. By adding AS numbers to the AS-path, you

can cause the route to be less preferred when compared to other routes based on the length of the
AS-path.

• Add a user-defined tag an automatically calculated tag to the route.
• Set the community attributes.
• Set the local preference.
• Set the MED (metric).
• Set the IP address of the next-hop device.
• Set the origin to IGP or INCOMPLETE.
• Set the weight.
• Set a BGP4 static network route.

When you configure parameters for redistributing routes into BGP4, one of the optional parameters is
a route map. If you specify a route map as one of the redistribution parameters, the device matches
the route against the match statements in the route map. If a match is found and if the route map
contains set clauses, the device sets the attributes in the route according to the set clauses.

To create a route map, you define instances of the map by a sequence number.

To define a route map, use the procedures in the following sections.

Entering the route map into the software

To add instance 1 of a route map named "GET_ONE" with a permit action, enter the following
command.

device(config)# route-map GET_ONE permit 1

device(config-routemap GET_ONE)#

Syntax: [no] route-map map-name permit | deny num

As shown in this example, the command prompt changes to the route map level. You can enter the
match and set clauses at this level.

The map-name is a string of characters that names the map. Map names can be up to 80 characters
in length.

The permit and deny parameters specify the action the device will take if a route matches a match
statement:

• If you specify deny, the device does not advertise or learn the route.
• If you specify permit, the device applies the match and set clauses associated with this route map

instance.

The num parameter specifies the instance of the route map you are defining.

To delete a route map, enter a command such as the following. When you delete a route map, all the
permit and deny entries in the route map are deleted.

device(config)# no route-map Map1

This command deletes a route map named Map1. All entries in the route map are deleted.

To delete a specific instance of a route map without deleting the rest of the route map, enter a
command such as the following.

device(config)# no route-map Map1 permit 10

This command deletes the specified instance from the route map but leaves the other instances of the
route map intact.
