Abstract

The embodiment of the invention discloses a method and a device of accessing virtual private network, relates to the field of communication technologies, and is capable of enabling a single user to access a plurality of VPNs (Virtual Private Network), and satisfying requirements of route isolation and information isolation among the VPNs. The method comprises the following steps of determining the virtual private network VPN to be accessed through user equipment according to account information of the user; transmitting a configuration message to a provider edge router PE, wherein the configuration message comprises an extension field, and the extension field comprises a virtual routing and forwarding instance VRF attribute value corresponding to the VPN; receiving acknowledgement information transmitted by the PE after configuration of the PE is completed; transmitting a service message to the VPN. The invention is suitable for the virtual private network VPN.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and device for accessing a virtual private network. Background technique [0002] VPN (Virtual Private Network, Virtual Private Network) is a virtual private network established on a public network, which has the same excellent security, reliability and ease of management as a private network. With the development of VPN, MPLS (Multi-protocol Label Switching, multi-protocol label switching) VPN appeared. In the MPLS VPN model, routers are divided into three types: CE (Customer Edge Router, user edge router), PE (Provider Edge Router, operator edge router) and P (Provider Router, operator backbone router), where CE is A component of the user network has an interface directly connected to the PE in the carrier's backbone network. The CE does not perceive the existence of the VPN and does not need to maintain the entire routing information of the VPN; the PE is the e...
