Abstract
In general, techniques are described for flooding VPLS traffic with a network device according to flood groups. The network device resides within a layer 3 (L3) network and includes a control unit that executes a virtual private LAN service (VPLS) protocol that enables a VPLS domain to operate over the L3 network. The network device further includes a plurality of packet forwarding engines, each of which include a plurality of interface cards that receive a layer 2 (L2) message originating from the L2 network. The packet forwarding engines associate the L2 packet with a configurable flood group, wherein the flood group defines criteria to determine which messages to associate to the flood group and indicates a set of the interface cards for forwarding the associated messages. The packet forwarding engines further flood the L2 packet via each interface card indicated by the associated flood group.
