Abstract
A method is provided in one example embodiment and may include receiving a frame at a Ethernet Virtual Private Network (EVPN) provider edge (PE) node via an attachment circuit link, wherein the frame is to be forwarded to a Virtual Private Local Area Network (LAN) Service (VPLS) PE node; determining whether the EVPN PE node is a designated forwarder for the attachment circuit link; forwarding the frame using at least one primary pseudowire label based on a determination that the EVPN PE node is the designated forwarder for the attachment circuit link; and forwarding the frame using at least one mirrored pseudowire label based on a determination that the EVPN PE node is not the designated forwarder for the attachment circuit link. The EVPN node can be in an all-active multi-homed configuration with at least one other EVPN PE node for a customer edge device.
