Problems solved by technology

In the prior art, when the link between router A31 and switch B35 and the link between router A31 and switch C36 fail, and after the link between router B32 and switch C36 and the link between router B32 and switch D37 fail, it is assumed Router A31 is the main router MASTER, so since router B32 is the backup router SLAVE, the VRRP users on VRRP1′ in router B32 will not be able to communicate with the outside normally, and if VRRP1′ in router B32 does not join VGMP, then the router The VRRP users connected to VRRP1' in B32 can communicate with the outside normally; this situation will lead to the problem that VGMP can't work normally, which reduces the reliability of the network

Embodiment Construction

[0029] The method described in the embodiment of the present invention mainly solves the unreliable problem of VRRP that has joined the VGMP protocol in some network environments, including the following steps, the VGMP master router regularly sends the VGMP that carries the VRRP status of all routers in the VGMP management group in the VGMP management group notification message, the VGMP backup router judges the state of the VGMP primary router VRRP according to the VGMP notification message of the VRRP state; according to the VRRP state of the VGMP primary router and the state of the corresponding VGMP backup router VRRP Adjustment.

[0030] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] FIG. 1 is a flowchart of a method for improving the reliability of the VGMP protocol according to an embodiment of the present invention. With reference to Fig. 1,...

Abstract

The disclosed method for improving VGMP reliability comprises: VGMP standby router receives VGMP message on VRPP state from the main VGMP router to decide the VRPP state of main VGMP router accordingly; if the state is INITIAL and the standby VRPP state is standby SLAVE, changes VRRP state of standby router into MASTER as main state.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a method, system and device for improving the reliability of the VGMP (VRRP Group Management protocol, Virtual Router Group Management Protocol) protocol. Background technique [0002] A LAN is a terminal access network, an important part of the Internet, and has a huge number of networks. The reliability of the LAN is mainly manifested in the reliability of the routing equipment connecting the two LANs, or the reliability of the LAN accessing the external network. Therefore, the inter-network reliability technology becomes the key to the reliable operation of the LAN. Although there are many protocols for link backup and self-repair on the Internet, these protocols are often not applied in the LAN. The largest host devices (PCs including some servers) do not support dynamic routing protocols, so the current link and route backup in the local area network ...
