Abstract

The disclosed apparatus may include a physical link that facilitates communication for a plurality of customer networks connected to a service provider network. The apparatus may also include a network device communicatively coupled to the physical link. The network device may identify first and second route-update messages that advertise a plurality of route targets representing the plurality of customer networks to at least one other network device within the service provider network. The network device may remove a route target from the first route-update message due at least in part to the physical link no longer facilitating communication for a customer network represented by the route target. The network device may then maintain the second route-update message intact despite the removal of the route target from the first route-update message. Various other apparatuses, systems, and methods are also disclosed.
