Abstract
The present application provides a method and a device for clearing a MAC forwarding entry. The method includes: detecting, by a first RB, that a topology of a network accessed by a local terminal changes; and sending, by the first RB, a first packet to a second RB, so that the second RB clears a corresponding forwarding entry after receiving the first packet, where the second RB refers to an RB configured with at least one VLAN the same as that of the first RB. According to embodiments of the present application, after the topology of the network accessed by the local terminal changes, MAC forwarding entries of relevant devices in a whole network can be cleared in time, thereby avoiding a forwarding error.
