Abstract: A virtual extensible local area network (VXLAN) packet forwarding method, device, and system, where the method includes setting, by a local VXLAN tunnel end point (VTEP) device based on a priority of a VXLAN tunnel, tunnel states of at least two VXLAN tunnels coupled to the local VTEP device, sending the tunnel states of the VXLAN tunnels to at least two peer VTEP devices, where the at least two VXLAN tunnels are in a one-to-one correspondence with the at least two peer VTEP devices, and separately confirming, by the at least two peer VTEP devices, the received tunnel states of the VXLAN tunnels. A VXLAN tunnel in an active state is in a working state, and a VXLAN tunnel in an inactive state is in a non-working state, thereby improving a redundancy protection capability of a VXLAN network.

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.
