Abstract

The invention discloses a method for updating the protocol state of a VRRP interface, a switch and a storage medium. By monitoring the state of the VLAN interface, when the VLAN interface is up, send the VLAN interface up event notification, and check whether there is any relevant configuration of the VLAN interface, if any, add a subclass for the VLAN interface interface; when the sub-interface is up, send the sub-interface up event notification, configure the corresponding IP address for the sub-interface, update the sub-interface status, send a VRRP multicast message, and update the protocol of the VRRP interface state. This enables real-time and accurate updating and fast switching of the status of the protocol of the VRRP interface without changing the independence of the existing modules.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a method for updating the state of a VRRP interface protocol, a switch and a storage medium. Background technique [0002] Virtual Router Redundancy Protocol (VRRP for short) is a routing protocol used to solve the phenomenon of single point of failure in the static gateway configuration in the local area network. It can dynamically assign the responsibility of a virtual router to one of the VRRP routers on the LAN. The VRRP router that controls the IP addresses of the virtual routers is called the master router, and it is responsible for forwarding packets to these virtual IP addresses. This election process provides a dynamic failover mechanism should the primary router become unavailable, which allows the virtual router's IP address to serve as the default first-hop router for end hosts. It is a LAN access device backup protocol. All hosts in a local area network...
