Abstract

See full text

An example egress network device includes at least one computer processor and a memory. The memory includes instructions that cause the at least one computer processor to receive messages from each of a plurality of ingress network devices. Each message specifies a multicast source as an anycast address that belongs to two or more sources, a multicast group, and a customer site identifier that uniquely identifies a customer network device via which the anycast address is reachable. The instructions cause the at least one computer processor to select, based on the customer site identifiers, one of the plurality of ingress network devices to which to send a multicast join message of a plurality of multicast join messages for the multicast source and multicast group. The instructions cause the at least one computer processor to send the multicast join message to the selected one of the plurality of ingress network devices.
