Usage Guideline The named community access list is a filter based on regular expressions. If the

regular expression matches the specified string representing the AS path of the

route, then the permit or deny condition applies. Use this command to define the

BGP access list globally, use the neighbor filter-list command in the router

configuration mode to apply a specific access list.

Multiple commands can be applied to a list name.

Example This example shows how to define an AS path access list named “mylist” to deny

access to the neighbor with AS number 65535.

Verify the settings by entering the show ip as-path access-list command.
