Abstract
A packet processing method includes sending, by the first provider edge (PE) device, a Media Access Control (MAC) entry update packet to a third PE device when a port of a first PE device that is connected to a customer edge (CE) device is switched from an activated state to a deactivated state, wherein the MAC entry update packet is sent to trigger the third PE device to delete a first MAC entry whose packet forwarding destination address is the first PE device, generating, through learning, a second MAC entry whose packet forwarding destination address is a second PE device, and forwarding a packet based on the second MAC entry.
