Example 7: Filter Routes with Route Maps

You can implement route filters with BGP route maps. BGP route maps are separated by
PBR route maps. BGP route maps support the following filter list:
• as-path
• community
• ip address prefix-list
• ipv6 address prefix-list
This example shows how to filter BGP routes with AS-PATH list.
