Problems solved by technology

However, in some cases, such as during a brief network shock, network devices may need to delete tunnels, learn neighbors, and establish tunnels. These processes take a long time
And this may lead to a longer period of interruption of network equipment, so that normal network services cannot be provided.

Abstract

The embodiment of the present invention provides a method and device for establishing a neighbor, which is applied to a tunnel module of any network device. The method includes: when receiving a tunnel deletion message, obtaining the destination address of the tunnel to be deleted; according to the destination address , judging whether it can be connected to the peer network device; if not, deleting the tunnel to be deleted; if yes, notifying the neighbor protocol module to establish a neighbor relationship with the peer network device according to the destination address of the tunnel to be deleted. The embodiments of the present invention can improve the efficiency of establishing neighbors and enable network equipment to provide normal network services.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a neighbor establishment method and device. Background technique [0002] ENDP (Enhanced Neighbor Discovery Protocol, Enhanced Neighbor Discovery Protocol) is a protocol for automatically discovering neighbors. The use of this protocol can greatly simplify network configuration and reduce the maintenance workload of network management staff. For example, a VTEP (VXLAN Tunnel End Point, VXLAN tunnel endpoint) in a VXLAN (Virtual eXtensible Local Area Network, scalable virtual local area network) can automatically discover neighbor VTEPs through ENDP, and automatically establish a neighbor relationship. [0003] In practical applications, after discovering neighbor network devices and establishing a neighbor relationship, a Tunnel (tunnel) can be automatically established between the local network device and the neighbor network device to exchange packets between ne...
