Problems solved by technology

[0005] However, practice has found that if the IS-IS routing protocol is run in the above-mentioned data center network, when the spine node receives the LSP from the leaf node, it will flood the LSP (Link State PDU (Protocol Data Unit, Protocol Data Unit) , link state message) message, after the leaf node receives the LSP message, it will flood all the spine nodes, resulting in excessive resource consumption

Abstract

The present invention provides a method and device for processing link state information. The method includes: receiving a first link state message LSP message from a Leaf interface, and performing route calculation according to the first LSP message; calculating the calculated The destination route whose outbound interface is the Leaf interface in the route is carried in the second LSP message, and the one second LSP message carries a plurality of the target routes; and the second LSP message is flooded to the Leaf node. The application of the embodiment of the present invention can reduce the number of flooding of LSP messages in the data center networking, and save system resources.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a link state information processing method and device. Background technique [0002] IS-IS (Intermediate System-to-Intermediate System, intermediate system to intermediate system) was originally designed by ISO (International Organization for Standardization, International Organization for Standardization) for CLNP (Connection-Less Network Protocol, connectionless network protocol) A dynamic Routing Protocol. In order to provide routing support for IP (Internet Protocol, Internet Protocol), IETF (Internet Engineering Task Force, Internet Engineering Task Force) carried out IS-IS in RFC (Request For Comments, a series of documents arranged by number) 1195 Expansion and modification, so that it can be applied in both TCP (Transmission Control Protocol) / IP and OSI (Open System Interconnection, open system interconnection) environments, called integrated IS-IS ...
