Abstract
An Ethernet Ring Protection (ERP) method is disclosed. The method includes: when a link on an Ethernet ring network is faulty, determining whether the faulty link is a link where a normally blocked port is located; and sending a first control message which carries first indication information to a ring node on the Ethernet ring network if the faulty link is the link where the normally blocked port is located, wherein the first indication information indicates that a forwarding table is not desired to be cleared by the ring node. Through the method according to the present invention, the broadcast traffic generated by unnecessary clearing of the forwarding table and self-learning is reduced effectively.
