ABSTRACT:
A method for implementing Layer 1 Virtual Private Network (L1 VPN) includes creating on a Provider Edge (PE) at least one Virtual PE which performs signaling exchange and routing exchange with a Customer Edge (CE) to support at least one L1 VPN service mode. A device corresponding to the method is also provided. With the inventive solution, appropriate service modes may be selected according to different demands of a user for L1 VPN services required, and VPEs and VCEs may be created dynamically on a PE and a CE to support various service modes, so as to satisfy the demands of the user. Information security and effective resource usage can also be ensured in supporting the various service modes.
