Abstract: A network device may receive a request seeking a location identifier for an endpoint identifier from a first router. The network device may determine that the endpoint identifier belongs to a dynamic endpoint identifier range associated with a plurality of routers. The request may be forwarded to the plurality of routers to discover a host having the endpoint identifier and a notification may be received from one of the plurality of routers reporting discovery of the host having the endpoint identifier. The network device may send an identifier of the one of the plurality of routers which reports discovery of the host to the first router as the location identifier for the endpoint identifier.

Abstract: Methods and network devices are disclosed for multicast traffic steering in a communications network. In one embodiment, a method includes generating a first tree connecting a source node for a multicast flow through a communications network to each of multiple destination nodes for the multicast flow. The communications network is configured to forward a multicast message based on bit values in a message bit array carried by the message, and the first tree comprises a first set of unicast paths from the source node to the destination nodes. The method further includes allocating a first tree identifier to the first tree and communicating the first tree identifier and associated forwarding information to each of multiple forwarding nodes within the communications network. An embodiment of a network device includes a processor operably coupled to one or more network interfaces and adapted to perform steps of the method.

Abstract: Techniques provided herein use aggregate endpoints in a virtual overlay network. In general, aggregate endpoints operate as a single receiving entity for certain packets/frames sent between different physical proximities of the virtual overlay network.
