US 12,184,545 B2 · Packet processing method and related apparatus

Abstract

This application provides a packet processing method and a network device. A third network device is multi-homed to a first network device and a second network device, the first network device is configured with a first physical MAC address and a virtual MAC address, the second network device is configured with a second physical MAC address and the virtual MAC address, and the virtual MAC address is used to forward a user data packet to a network side. The method includes: a first network device receives a protocol packet from a third network device, where the protocol packet includes the second physical MAC address; and the first network device forwards the protocol packet to the second network device based on the second physical MAC address. Thus, the protocol packet can be normally forwarded without special configuration on a server, so that a cumbersome configuration process is avoided.

Dependent claims

A packet processing method comprising:

receiving, by a first network device in a network system, a protocol packet from a third network device multi-homed to the first network device and a second network device, wherein the protocol packet comprises a second physical media access control (MAC) address associated with the second network device, wherein the network system comprises the first network device, a second network device, and the third network device, wherein the first network device is configured with a first physical MAC address and a virtual MAC address, wherein the second network device is configured with the second physical MAC address and the virtual MAC address, wherein the virtual MAC address is used to forward a user data packet to a network side, wherein the protocol packet received by the first network device from the third network device comprises a time to live (TTL), and wherein the TTL in the protocol packet forwarded by the first network device to the second network device is not decreased by 1;
and
forwarding, by the first network device, the protocol packet to the second network device based on the second physical MAC address.

A third network device in a network system, the third network device comprising a processor and a memory, wherein the memory is configured to store instructions, and the processor is configured to execute the instructions in the memory, so that the third network device performs operations comprising:

sending a request message, wherein the request message comprises a physical internet protocol (IP) address of a first network device, wherein the network system comprises the first network device, a second network device, and the third network device, and wherein the third network device is multi-homed to the first network device and the second network device;
receiving a response message, wherein the response message comprises a physical media access control (MAC) address of the first network device, and wherein there is a correspondence between the physical IP address of the first network device and the physical MAC address of the first network device;
and
sending a protocol packet, wherein the protocol packet comprises the physical MAC address, and wherein the physical MAC address is used by the first network device to forward the protocol packet to the second network device.

1 more element
