发明名称 Redundancy at a Virtual Provider Edge Node that faces a Tunneling Protocol Core Network for Virtual Private Local Area Network (LAN) Service (VPLS)
摘要 In one embodiment, a method includes receiving configuration data at a particular node of a first set of multiple nodes. The configuration data includes data that indicates a particular zero or more instances for which the particular node is primary among multiple virtual local area network (VLAN) instances to be forwarded. It is determined whether a VLAN indicated in a data packet received at the particular node is included in the particular instances for which the particular node is primary. If so, then the data packet is forwarded. In another embodiment, multiple nodes are configured to perform as a single virtual node, and the single virtual node is configured to forward data packets for the multiple VLAN.
