Abstract: Methods, apparatus, systems and articles of manufacture to reflect routes from a virtual route reflector are disclosed. An example method includes requesting, at a virtual route reflector remote from an autonomous system, topology information and external route information from the autonomous system. The external route information identifies a plurality of border routers through which a remote destination can be reached. The example method also includes selecting, using the topology information, a first path from among a plurality of paths emanating from a selected node in the autonomous system, the plurality of paths exiting the autonomous system at respective border routers of the plurality of border routers. The example method further includes advertising, from the virtual route reflector to a client router in the autonomous system, a route to the remote destination, the route including a first border router at which the first path exits the autonomous system.

Abstract: Routes are reflected from a virtual route reflector. For instance, topology information and external route information are requested by a virtual route reflector remote from an autonomous system. The external route information identifies border routers through which a remote destination can be reached. Using the topology information, a first path can be selected from among paths emanating from a selected node in the autonomous system, the paths exiting the autonomous system at respective border routers of the border routers. Further, a route to the remote destination can be advertised from the virtual route reflector to a client router in the autonomous system, the route including a first border router at which the first path exits the autonomous system.
