Address resolution optimization procedure to effect a gradual cutover from a provider bridge network to a VPLS or provider backbone bridging network |
摘要 |
A method and apparatus that operates two bridging protocols in a hybrid bridging node is described. The operation of the two bridging protocols in the hybrid node allows for an incremental transition of a provider bridging network from operating a legacy bridging protocol that shares MAC addresses to a bridging network that operates VPLS and/or PBB bridging protocols. The hybrid bridging node selectively broadcasts address resolution packets and unicast packets with unknown MAC addresses from the nodes operating VPLS and/or PBB to nodes operating a legacy bridging protocol.
