Abstract:
Examples of the present disclosure provide a packet forwarding method and apparatus applied to a VXLAN. In examples of the present disclosure, redundancy protection for a VXLAN IP gateway is realized by deploying a VXLAN IP gateway group in a VXLAN, and a first VTEP in the VXLAN can ensure each VXLAN IP gateway in the VXLAN IP gateway group to learn an ARP entry of a same VM by establishing a VXLAN control tunnel from the first VTEP to each VXLAN IP gateway of the VXLAN IP gateway group and establishing a VXLAN data tunnel from the first VTEP to the VXLAN IP gateway group, thus ensuring the VXLAN IP gateway correctly forwards the service packet.

Claim (Index 7):
A packet forwarding apparatus applied to a virtual extensible local area network (VXLAN), wherein, the apparatus is applicable to a first VXLAN tunnel end point (VTEP), comprising:\n a tunnel unit, to establish a VXLAN data tunnel between the first VTEP and a VXLAN IP gateway group, a source address of the VXLAN data tunnel is a VTEP IP address of the first VTEP, a destination address of the VXLAN data tunnel is a VTEP group IP address of the VXLAN IP gateway group, the VXLAN IP gateway group comprises N VXLAN IP gateways in a VXLAN, wherein N is larger than 1, the VXLAN IP gateways are second VTEPs in the VXLAN, different VXLAN IP gateways have different VTEP IP addresses; and to establish a VXLAN control tunnel between the first VTEP and each VXLAN IP gateway in the VXLAN IP gateway group, a source address of the VXLAN control tunnel is the VTEP IP address of the first VTEP, a destination address of the VXLAN control tunnel is the VTEP IP address of the VXLAN IP gateway, the VXLAN control tunnel and the VXLAN data tunnel are associated with a same VXLAN identifier; and a packet unit, to transmit an ARP packet respectively via the VXLAN data tunnel and the VXLAN control tunnel.
