Abstract
A Provider Edge (PE) node is configured to provide a Layer 2 Virtual Private Local Area Network (LAN) service (VPLS) having a simplified control plane. The PE node includes circuitry configured to receive a packet from a second PE node in the network, wherein the packet includes (1) a Destination Media Access Control (MAC) address associated with a destination Customer Edge (CE) node, (2) a source MAC address associated with a source CE node, and (3) a Virtual Local Area Network (VLAN) Identifier used to represent one of the second PE node and a multihome configuration including the second PE node, and learn the source MAC address associated with the source CE node as being reachable via the one of the second PE node and the multihome configuration.
