DHCP relay working method and device in MLAG environment and medium

Abstract

The invention discloses a DHCP (Dynamic Host Configuration Protocol) relay working method, DHCP relay equipment and a medium in an MLAG (Multi-Link Aggregation) environment, belongs to the technical field of cross-equipment link aggregation, and is used for solving the technical problem that a large number of DHCP synchronous messages occupy CPU (Central Processing Unit) resources when the back-and-forth paths of the existing DHCP response messages are inconsistent. The method comprises the following steps: carrying out mounting configuration of the same IP address on first virtual local area networks of an MLAG main device and an MLAG standby device in a DHCP relay agent to obtain a third virtual local area network; performing broadcast processing related to the MLAG main equipment and the MLAG standby equipment on a DHCP request message in the DHCP client, and determining a DHCP relay proxy IP address; and based on the IP address of the DHCP relay agent, the DHCP response message is sent to the DHCP client.
