Abstract: A method and a device for preventing repeated refreshing of an address table of an Ethernet ring network node are provided. After a state of a port of the Ethernet ring network node is changed to a blocked state, it is determined that whether the Ethernet ring network node is an RPL neighbor node and whether the blockage is triggered by an RPL Blocked protocol frame. If so, the Ethernet ring network node stores refreshed record information corresponding to its two ports on the ring. The problem that an RPL neighbor node refreshes an address table repeatedly in the scenario of switchback of an Ethernet ring network can be effectively solved via the aforementioned method and device, thereby reducing flow broadcast during protection switching of the Ethernet ring network and improving the switching efficiency.
