Abstract
This application discloses an MLAG link failure switching apparatus and method. The apparatus includes a chip. The chip is configured to: generate a forwarding database, and forward a packet based on the forwarding database, where the forwarding database includes a first forwarding database, a second forwarding database, and a third forwarding database. The apparatus switches a faulty MLAG link by modifying a value of an active-standby switching flag corresponding to the faulty link in the first forwarding database, thereby reducing a link switching time and improving link switching efficiency.
