Problems solved by technology

This method of dynamically refreshing a large number of VPN forwarding entries is not only complicated to operate, but also takes a certain amount of time to refresh a large number of VPN forwarding entries, so it will also cause VPN services to fail to recover quickly after the LSP tunnel changes.

Embodiment Construction

[0045] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0046] The basic idea of ​​the present invention is: fix the LSP tunnel ID used by VPN, so that the LSP tunnel ID information in the VPN forwarding table is fixed, so that when the LSP tunnel changes, it only needs to refresh the NHLFE table related to the changed LSP tunnel Items without refreshing all related VPN forwarding table items, thereby reducing the complexity of information maintenance, saving refresh time, and enabling VPN services to be quickly restored after the LSP tunnel changes.

[0047] In order to realize the fixed LSP tunnel ID, the PE needs to bind an LSP tunnel ID to the destination of each LSP tunnel (that is, each peer PE). Wherein, the LSP tunnels include not only established LSP tunnels but also unestablished LSP tunnels. For ...

Abstract

The invention discloses a method for managing label switching path (LSP) tunnel information, including: respectively binding an LSP tunnel identification for every LSP tunnel destination, wherein, the LSP tunnel destination is in one-to-one correspondence with the LSP tunnel identification; acquiring the LSP tunnel identification bond to the LSP tunnel destination and recording into the VPN forwarding table, during establishing an VPN forwarding table arriving the LSP tunnel identification; during establishing the LSP tunnel, using the LSP tunnel identification bond to the LSP tunnel destination to identify the LSP tunnel, and establishing corresponding NHLFE table for the LSP tunnel; and refreshing the NHLFE table corresponding to the variation of the LSP tunnel, when the LSP tunnel changes. The invention also discloses an apparatus for managing LSP tunnel information. The invention can reduce information maintenance complexity and reduce VPN service recovery time, when the LSP tunnel changes.

Description

technical field [0001] The present invention relates to multi-protocol label switching (MPLS, Multi Protocol Label Switch) technology, in particular to a label switching path (LSP, Label Switch Path) tunnel information management method and device. Background technique [0002] MPLS is a technology that uses labels to forward packets. It has the advantages of fast forwarding, QoS guarantee, and multi-service support. It plays an important role in the next-generation telecommunications network. MPLS VPN is a virtual private network (VPN, Virtual Private Network) based on MPLS technology. It applies MPLS technology to network routing and switching equipment, and can be used to construct broadband Intranet and Extranet to meet various flexible business requirements. [0003] Figure 1 shows a typical network diagram of MPLS VPN, including: customer edge equipment (CE, CustomEdge), backbone network edge equipment (PE, Provider Edge) and backbone network core equipment (P, Provide...
