Configure a Route Map

You can optionally configure a route map to filter and update routes. Associate the route map with a BGP peer to filter routes. You can configure multiple route maps but you can apply only one route map to a peer. If filtering needs are identical, you can use the same route map for inbound and outbound traffic.
The branch ION device filters received routes based on the route map. Filters may be based on a prefix list, AS path list, or community list. For example, a peer may advertise 1000 routes, but you may be interested in only 20 routes from this peer. You can apply conditions to filter the 20 routes of interest to the ION device.
Route maps are auto-generated for core and edge peers. You need to create route maps for a classic peer in a branch or a data center. Using match and set criteria and permit and deny clauses, the ION device accepts or denies routes that are advertised.
