摘要
Methods and systems to operate an Ethernet ring protection switching (ERPS) network. In one embodiment, a method performed by a network device in the ERPS network device is disclosed. The ERPS network comprises a major ring and a sub-ring, where the network device is a first interconnection network device that is on both major ring and sub-ring. The method comprises determining that a topology change notification is received from the sub-ring, identifying a link that is coupled to the network device and that is towards a second interconnection network device, where the second interconnection network device is also on both major ring and sub-ring. The method further comprises terminating the topology change notification and transmitting a first message using the link towards the second interconnection network device, where the first message is a filtering database (FDB) flush message.
