Abstract: This application discloses a packet transmission method, a network device, and a system. After receiving a first packet, a first network device obtains a tunnel header corresponding to the first packet. The first network device encapsulates a tunnel header in an IPv6 header by encapsulating the IPv6 header in the first packet, to obtain a second packet. The first network device sends the second packet to a second network device, so that the second network device forwards the packet based on the tunnel header included in the IPv6 header. In this application, the IPv6 header is used to carry the tunnel header.

Abstract: This application discloses a VXLAN packet transmission method, a network device, and a system. After receiving a first packet, a first network device obtains a VNI corresponding to the first packet. The first network device encapsulates the VNI in an IPV6 header by encapsulating the IPV6 header in the first packet, to obtain a second packet. The first network device sends the second packet to a second network device, so that the second network device forwards the packet based on the VNI included in the IPV6 header. In this application, the IPV6 header is used to carry the VNI, and no additional UDP header needs to be encapsulated to carry the VNI.
