Abstract
The disadvantages of traditional VPN(Virtual Private Network) and the advantages of MPLS L2 VPN(Layer2 VPN based on multiple protocol label switch) are discussed.Data forwarding and the control are the two problems to be solved to implement L2 VPN based on MPLS.Finally,the developing trend of MPLS L2 VPN is explained.
