Problems solved by technology

However, R2 continues to send handshake messages to R1. When R1 receives the handshake message, it will establish a neighbor relationship with R2 again, and then R2 will cancel the neighbor relationship. This will cause the neighbor relationship to fluctuate and cause adverse effects on the network. influences

Abstract

The embodiment of the invention discloses a unidirectional link data processing method and device. A UDL is disposed between first network equipment and second network equipment. The method comprises the steps: enabling the first network equipment to receive a first handshaking message transmitted by the second network equipment; building a neighborhood relation with the second network equipment, and transmitting a second handshaking message, so as to enable the second network equipment to obtain the second handshaking message through connected third network equipment, wherein the first network equipment calculates the reachability from the first network equipment to the second network equipment; enabling the NBR (neighborhood relation) corresponding to a calculation result not to be published if the calculation result is Not Reachable, thereby maintaining the NBR with the second network equipment. Therefore, the first network equipment serving as a receiving end in a unidirectional link is used for calculating the reachability, and the NBR is not published if the calculation result is Not Reachable, thereby avoiding the fluctuation of the NBR between the first and second network equipment.

Description

technical field [0001] The invention relates to the communication field, in particular to a data processing method and device for a unidirectional link. Background technique [0002] Before data transmission, two network devices connected in the network need to exchange handshake (hello) messages to confirm whether the link status with the opposite end meets the conditions for establishing a neighbor relationship, thereby establishing a neighbor relationship with each other. This confirmation is a two-way confirmation. For example, the two connected network devices are network device A and network device B respectively. Network device A sends a handshake message carrying the location information of network device A to network device B. Network device B receives The handshake message can confirm that the link from network device A to network device B meets the above conditions, thereby establishing a neighbor relationship with network device A. Network device B returns a han...
