Multicast join message processing by multi-homing devices in an ethernet VPN

Abstract:

In some examples, a method includes receiving, by a first provider edge (PE) device of a layer 3 network, configuration data configuring the PE device to provide, via an Ethernet segment with an edge device, active-active multi-homing layer 2 (L2) virtual bridge connectivity to the edge device using an Ethernet Virtual Private Network (EVPN) instance; receiving, by the first PE device, a multicast Join message for multicast traffic, the multicast Join message identifying a second PE device that also participates in the EVPN instance; processing, by the first PE device, the multicast Join message to generate multicast forwarding state; and forwarding, by the first PE device based at least on the multicast forwarding state, the multicast traffic.
