Embodiment Construction

[0021] In order to make the technical solutions and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0022] In the embodiment of the present invention, a method for updating an adjacency entry is proposed, which can realize the linkage between the route and the adjacency entry, and solve the problem of the time difference between the learning of the route and the adjacency entry.

[0023] see figure 1 , figure 1 It is a schematic flow chart of updating an adjacency table entry in the embodiment of the present invention. The specific steps are:

[0024] In step 101, a router establishes a neighbor through a routing protocol.

[0025] Among them, the routing protocol includes: OSPF protocol or OSPFv3 protocol, IS-IS protocol, RIP protocol or RIPng protocol; OSPF protocol supports IPv4, OSPFv3 protocol supports IPv6, IS-IS protocol supports b...

Abstract

The invention discloses a neighbor table item updating method which includes: when a router determines absence and invalidity of a neighbor table item corresponding to an IP (internet protocol) address of a neighbor, triggering the neighbor table item corresponding to the IP address of the neighbor to be established, marking the state of the neighbor to the asynchronous state and informing all neighbors; if the neighbor table item corresponding to the IP address of the neighbor is established successfully and updated, restoring the state of the neighbor to the synchronous state and informing all the neighbors; and when routing computation is performed locally, preferably selecting routers with the neighbor synchronous state and issuing the routers to FIB (forwarding information base). Based on the same inventive concept, the invention further provides the router. By the aid of the neighbor table item updating method and the router, linkage of the routers and neighbor table items can be achieved, and the problem of time difference of the routers and neighbor table item studying is solved.

Description

technical field [0001] The present application relates to the technical field of communication, in particular to a method and a router for updating an adjacency table entry. Background technique [0002] The current mainstream routing protocols mainly include Open Shortest Path First (OSPF) protocol or OSPFv3 protocol, Intermediate System to Intermediate System Routing Protocol (IS-IS) protocol, Routing Information Protocol (RIP) protocol or RIPng protocol, and static routing. In high-level applications, fast convergence is an important index to measure the quality of a routing protocol. One of the important indicators is no packet loss on the switchback link. [0003] For the OSPF protocol, IS-IS protocol, and RIP protocol of point-to-point or point-to-multipoint networks, during the process of establishing neighbors, the protocols usually do not send unicast packets, and thus do not trigger the learning of peer adjacency entries; , when the outbound interface and next ho...
