摘要： A ring network with an automatic protection switching domain includes a control VLAN and at least one data VLAN. A master node in the ring is connected to at least one transit node. Each node in the ring network is linked to an adjacent node by a primary port or a secondary port. The master node receives notification of a fault via the control VLAN, the fault indicating a failed link between adjacent nodes. In response, the master node unblocks its secondary port to traffic on the data VLAN(s). The forwarding database entries on the master node and on the transit node(s) are flushed. Data traffic is flooded to the ring network until forwarding database entries on the master node and on the transit node(s) have been reestablished.
