Match Examples Using ACLs

The following sections show some detailed examples of how to configure route maps that include match statements that match on ACLs.

Matching Based on AS-Path ACL

To construct match statements for a route map that match based on AS-path information, use either of the following methods.

USING THE CLI

To construct a route map that matches based on AS-path ACL 1, enter the following commands:

HP9300(config)# route-map PathMap permit 1

HP9300(config-routemap PathMap)# match as-path 1

Syntax: match as-path <num>

The <num> parameter specifies an AS-path ACL and can be a number from 1 – 199. You can specify up to five AS-path ACLs. To configure an AS-path ACL, use the ip as-pathaccess-listcommand. See “Defining an AS- Path ACL” on page 10-47.

USING THE WEB MANAGEMENT INTERFACE
