Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] Such as figure 1 As shown, the MPLS VPN includes: a backbone network core router 11 , a backbone network edge router 12 , and a user-side edge router 13 . Among them, the backbone network core router 11 is used for forwarding data packets in the network. The backbone network edge router 12 is used to store VRF, process VPN-IPv4 routing, and is the main body of VPN service processing. The backbone network core routers and the backbone network edge rout...

Abstract

The invention discloses a method and device for MPLS VPN network topology discovery, relates to the technical field of network management, and can solve the problem that the topology diagram generated in the prior art can only display part of the connection relationship of network equipment. The method of MPLS VPN network topology discovery includes: obtaining the configuration information of each network device; determining the type of the network device according to the configuration information of the network device; determining the network According to the interface information in the VRF configuration information of the PE, determine the CE connected to the PE; according to the RT parameter in the VRF configuration information of the PE, determine the connection between different PEs. Connection relationship: Generate a topology map according to the connection relationship among P, PE, and CE in the network. The invention is applicable to the network topology discovery process of MPLS VPN.

Description

technical field [0001] The invention relates to the technical field of network management, in particular to a method and device for MPLS VPN network topology discovery. Background technique [0002] VPN (Virtual Private Network, virtual private network) technology can use the public network to set up a private network to ensure the security of communication between the headquarters and branches of the enterprise and between different enterprises. At present, MPLS VPN based on MPLS (Multi-Protocol Label Switching) technology is the most advanced VPN in terms of flexibility, scalability, and security, and is widely used in enterprise interconnection scenarios. [0003] In practical application, in order to ensure the normal operation of MPLS VPN and quickly locate the fault node after its failure, it is necessary to discover the network topology of MPLS VPN. [0004] In the prior art, the method of MPLS VPN network topology discovery is: use RT (Route Target, route target) as...
