Configure BGP4 Route Map Matching on an AS-path

You can configure a route map that matches on a specified AS-path access control list (ACL).

Before you begin

The AS-path ACL must be configured using the ip as-path access-list command.

Procedure

Access global configuration mode.
```
device# configure terminal
```
Create a route map instance and allow a matching pattern.
```
device(config)# route-map myaclroutemap1 permit 10
```
This example creates a route map instance called myaclroutemap1 and allows a matching pattern of 10.
Configure the route map to match on an AS-path ACL.
```
device(config-route-map-myaclroutemap1/permit/10)# match as-path myaspath
```
This example configures the route map to match on the AS-path ACL called myaspath.

Example

The following example summarizes the commands in this procedure.

device# configure termnial
device(config)# route-map myaclroutemap1 permit 10
device(config-route-map-myaclroutemap1/permit/10)# match as-path myaspath
