Abstract
A method for accessing VPN using PW Emulation Edge-to-Edge Virtual Leased Line includes: configuring a first PW ID in a first Provider Edge Device that hosts a VSI, and an IP address of a second Provider Edge Device that hosts an PW Emulation Edge-to-Edge Virtual Leased Line associated with the PW ID; sending a second PW ID of the second Provider Edge Device to the first Provider Edge Device; determining whether the second PW ID of the second Provider Edge Device matches the first PW ID of the first Provider Edge Device, if it matches, setting the state of the PW between the first Provider Edge Device and the second Provider Edge Device; delivering a Forwarding Table by the first Provider Edge Device; establishing a bi-directional connection between the PW Emulation Edge-to-Edge Virtual Leased Line and the VSI. A Virtual Private System, a first Provider Edge Device, and a second Provider Edge Device are also provided.
