Configuring L2VPN
Context
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.
Virtual leased line (VLL) technology emulates leased lines on an IP network to provide inexpensive, asymmetrical digital data network (DDN) services. As a point-to-point (P2P) L2VPN technology, VLL can support almost all link layer protocols.
For details about L2VPN, see VLL Configuration in the S2720, S5700, and S6700 V200R019C10 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
