Abstract
The present disclosure discloses a method for preventing repeated updating of an address table in Ethernet ring network protection, including: an Ethernet ring network node sends an Ethernet ring network protection protocol frame and encapsulates its own node information into the Ethernet ring network protection protocol frame; an Ethernet ring network node receives the Ethernet ring network protection protocol frame and matches the node information encapsulated in the received Ethernet ring network protection protocol frame with its own node information; and when the matching is successful, the Ethernet ring network node does not update the address table. The present disclosure further discloses a system for preventing repeated updating of an address table in Ethernet ring network protection. In the system, a matching unit is used for matching the node information encapsulated in the received Ethernet ring network protection protocol frame with the node information of an Ethernet ring network node itself; and when the matching is successful, the Ethernet ring network node does not update the address table. Through the method and system of the disclosure, the problem of repeated updating of an address table in Ethernet ring network protection in the scenario of requesting local protection switching can be solved.
