Figure 27 Distributing Network Filters in Access Lists and Route Maps
Incoming and Outgoing Route Maps
You can have two types of route maps: incoming and outgoing. A BGP peer router can be
configured to support up to eight route maps in the incoming route map list and outgoing route map
list.
If a route map is not configured in the incoming route map list, the router imports all BGP updates.
If a route map is configured in the incoming route map list, the router ignores all unmatched
incoming updates. If you set the action to deny, you must add another route map to permit all
unmatched updates.
Route maps in an outgoing route map list behave similar to route maps in an incoming route map
list. If a route map is not configured in the outgoing route map list, all routes are advertised or
permitted. If a route map in the outgoing route map list is set to permit, matched routes are
advertised and unmatched routes are ignored.
