METHOD, SYSTEM AND EQUIPMENT FOR ACCESSING VISUAL PRIVATE NETWORK

摘要

A method, system and equipment for accessing layer 2 visual private network (L2VPN). The method involves establishing a PPP connection of customer premise equipment and an access server through a bridge control protocol (BCP) way (101). A data message of a customer is transmitted to a corresponding L2VPN according to pre-set corresponding rules based on customer connecting information (102). The method achieves accessing of L2VPN by only supporting PPP connected low speed network or leased network, because layer 2 data packet is carried in the PPP connection by BCP way. Different customers can be distinguished through the physical circuit mark connected by PPP or field mark dialed by customer, so as to perform different processes.
