Configuring L2VPN

Configuring L2VPN


After a Dot1q termination sub-interface is configured, you need to configure the virtual private network (VPN) service on the sub-interface so that users at both ends of the L2VPN can communicate with each other.

L2VPN includes Virtual leased line (VLL), Pseudo-Wire Emulation Edge to Edge (PWE3), and Virtual Private LAN Service (VPLS).
  • VLL technology emulates leased lines on an IP network to provide inexpensive, asymmetrical digital data network (DDN) service. As a point-to-point (P2P) L2VPN technology, VLL can support almost all link layer protocols.
  • PWE3 is an implementation mode of VLL and an extension of the Martini protocol. PWE3 reduces signaling costs and defines multi-segment PWs (MS-PWs), making networking modes more flexible.
  • VPLS technology implements multipoint-to-multipoint VPN networking. Using VPLS technology, an ISP can provide Ethernet-based multipoint-to-multipoint services for users through an MPLS backbone network.

For details about L2VPN, see VLL Configuration, PWE3 Configuration, and VPLS Configuration in the S7700 and S9700 V200R011C10 Configuration Guide - VPN.

A Dot1q termination sub-interface can be bound to a VLL that provides homogeneous or heterogeneous transport in the following modes:
  • Local Kompella connection
  • Remote Kompella connection
  • Local Martini connection
  • Remote Martini connection
A Dot1q termination sub-interface supports the following VPLS connections:
  • Martini VPLS
  • Kompella VPLS
