Abstract

Embodiments of the present invention relates to a method and device for updating VPN routing. A method for updating VPN routing comprises: a provider edge PE device determining a management state of a virtual private network VPN; the PE device informing a peer PE device of the management state of the VPN, so that the peer PE device updates, according to the management state of the VPN, routing information of the VPN. The routing processing on the VPN is implemented through informing of the management state of the VPN, so that it is not required to perform one-by-one updating on the VPN routing, thereby implementing a series of expanded functions such as VPN routing rapid updating and revoking, and solving the problems of a large amount of message processing and service convergence.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a VPN route update method and device. Background technique [0002] VPN (Virtual Private Network, Virtual Private Network) establishes a temporary and secure connection through a public network (usually the Internet). [0003] BGP (Border Gateway Protocol, Border Gateway Protocol) / MPLS (Multiprotocol Label Switching, Multiprotocol Label Switching) IP (Internet Protocol, Internet Protocol) VPN is a kind of L3VPN (Layer 3Virtual Private Network, Layer 3 Virtual Private Network), which uses BGP advertises VPN routes on the SP (Service Provider, service provider) backbone network, and uses MPLS to forward VPN packets on the service provider backbone network. The IP here means that the VPN bears IP packets. [0004] The basic model of BGP / MPLS IP VPN consists of three parts: [0005] CE (Customer Edge, user edge) equipment: has an interface directly connected to the ...
