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 9):
A packet forwarding apparatus for executing the method of  claim 3 , comprising:\n a receiving unit, to receive an ARP packet transmitted by the first VTEP; an ARP entry unit, to determine whether an outer destination IP address in a VXLAN encapsulation of the ARP packet is the VTEP IP address of the VXLAN IP gateway; if the outer destination IP address in the VXLAN encapsulation of the ARP packet is not the VTEP IP address of the VXLAN IP gateway, learn an ARP entry according to the ARP packet; and if the outer destination IP address in the VXLAN encapsulation of the ARP packet is the VTEP IP address of the VXLAN IP gateway, modify the outer destination IP address to the VTEP group IP address, and learn an ARP entry according to the modified ARP packet.
