EVPN TENANT DOMAIN TRANSIT NETWORK FOR MULTICAST TRAFFIC

Abstract

Techniques for operating a network device are provided. In some embodiments, a method may comprise: forwarding multicast data packets from a source in a first customer network to a receiver in a second customer network; detecting that another PE device is forwarding the multicast data packets, wherein: Protocol Independent Multicast (PIM) is enabled on supplemental bridge domain (SBD) logical interfaces of the PE device and the another PE device, the PE device and the another PE device are PIM neighbors, and the PE device and the another PE device communicate with each other and with the receiver using the PIM protocol through an Ethernet virtual private network (EVPN). The method may further comprise: determining the another PE device is an assert winner from among the PE device and the another PE device based on at least one PIM assert message, the another PE device forwarding the multicast data packets.
