Abstract: A packet processing method, a device, and a system are disclosed. In the method, a first provider edge (PE) device receives a first virtual extensible local area network (VXLAN) packet through a first point-to-point (P2P) VXLAN tunnel between the first PE device and a third PE device A customer edge (CE) device is dual-homed to the first PE device and a second PE device respectively through a first Ethernet link and a second Ethernet link. The first PE device forwards the first VXLAN packet to the second PE device through a third P2P VXLAN tunnel from the first PE device to the second PE device when there is a fault on the first Ethernet link. The first Ethernet link connected to the first PE device and a link formed by the third P2P VXLAN tunnel and the second Ethernet link have a primary/secondary relationship.
