Abstract

The embodiment of the invention provides a distributed gateway backup processing method and network equipment. The method comprises the following steps that: first network equipment receives an ARP (Address Resolution Protocol) update route message sent by second network equipment, wherein the ARP update route message is constructed according an EVPN (Ethernet Virtual Private Network) protocol; and the first network equipment acquires ARP table entries learned by the second network equipment according to the ARP update route message, and generates or updates the ARP table entries in the first network equipment, wherein in a first virtual local area network (VLAN), the first network equipment is currently a non-DF (non-Designated Forwarder) elected according to the EVPN protocol, and the second network equipment is currently a DF (Designated Forwarder) elected according to the EVPN protocol. In the embodiment of the invention, selection of active and standby gateways and backup of ARP information can be finished through network architecture of an EVPN without establishment of a special channel for electing active and standby gateway equipment or establishment of a special channel for backing up the ARP message, so that resources are saved; configuration is simplified; and the operation and maintenance difficulty is lowered.

Description

technical field [0001] The invention relates to communication technology, in particular to a distributed gateway backup processing method and network equipment. Background technique [0002] Ethernet Virtual Private Network (Ethernet Virtual Private Network, referred to as EVPN) refers to the cross-Internet Protocol (Internet Protocol, referred to as IP) or Multi-Protocol Label Switching (Multi-Protocol Label Switching, referred to as MPLS) bearer network, which connects local area networks (Local Area Network, referred to as LAN) of users in different regions. Together, these LANs can work as one LAN. Specifically, EVPN is composed of an operator's IP or MPLS bearer network and different LANs of users. The LANs of users are independent of each other and need to rely on the bearer network to realize intercommunication. Among them, the device that bears the network connection to the user's LAN and provides virtual private network (Virtual Private Network, VPN for short) serv...
