About this task
BGP peers and route maps can reference a single IP based access
list. Apply IP access lists to both inbound and outbound route updates. Every route
update is passed through the access list. BGP applies each rule in the access list
in the order it appears in the list. When a route matches a rule, the decision to
permit or deny the route is applied. No additional rules are processed.
