Problems solved by technology

[0023] To sum up, when the original fragmentation of the local device is full of other information such as routes, although the extended fragmentation is enabled, when a new neighbor is established, the neighbor TLV information may still fail because there is no space for storage. Added to the local LSDB, resulting in the loss of neighbor information, so that the peer device cannot obtain the routing information of the local device, affecting the realization of network communication

Embodiment Construction

[0063] As mentioned in the background technology, due to the limited storage space of the original fragment in the router, when the original fragment space is occupied by too much routing information, the router will not be able to store new neighbor information, and the newly added neighbor will not be correct. Calculate the route, thus causing the defect of traffic forwarding failure.

[0064] In order to solve the above problems, the present invention proposes a method for storing neighbor information, which is applied to a system including multiple routers. Neighbor relationships are established between multiple routers, and the routers contain multiple original fragments and extended fragments.

[0065] Such as Figure 4 As shown, it is a schematic flow diagram of a neighbor information storage method proposed by the present invention, which specifically includes the following steps:

[0066] Step S401 , the router selects one original fragment from its own original frag...

Abstract

The invention discloses a method for storing neighbor information and a device thereof, aiming at overcoming the defect of impassable flow rate retransmission caused by being not capable of accurately calculating a route by the new added neighbor after the new neighbor information can not be stored since too much route information fully occupies the original slicing space. The method can ensure the neighbor information to be stored in a preferential way, so as to lead the route information to be calculated normally and the flow rate to be transmitted normally, thus enhancing the reliability of IS-IS protocol.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a neighbor information storage method and device. Background technique [0002] IS-IS (Intermediate System-to-Intermediate System intra-domain routing information exchange protocol, intermediate system to intermediate system intra-domain routing information exchange protocol) was originally ISO (International Organization for Standardization, International Organization for Standardization) as CLNP (ConnectionLess Network Protocol, A dynamic routing protocol designed as a connectionless network protocol. [0003] In order to provide routing support for IP, IETF (Internet Engineering Task Force, Internet Engineering Task Force) has expanded and modified IS-IS in RFC 1195, so that it can be applied to TCP (Transmission Control Protocol, Transmission Control Protocol) In the environment of / IP (Internet Protocol, Internet Protocol) and OSI (Open System Interconnection, Open S...
