Abstract:
In one embodiment, a network device may participate in an election process to elect one of two or more Provider Edge devices of a Redundancy Group to be a Designated Forwarder for the Redundancy Group, where the Redundancy Group is in a Service Provider network, and where the Redundancy Group serves a Customer Edge device of a customer network. The network device may forward multi-destination traffic to the Customer Edge device according to whether the network device is elected to be the Designated Forwarder for the Redundancy Group. Multi-destination traffic may include multicast traffic, broadcast traffic, or destination unknown unicast traffic.
