Virtual Private LAN Service (VPLS)
In Chapter 11, "Any Transport over MPLS (AToM)," you were introduced to the implementation of Layer 2 VPN using like to like or any to any, point-to-point Layer 2 circuits using AToM. This chapter introduces you to the implementation of multipoint Ethernet Layer 2 VPNs using virtual private LAN services (VPLS). This chapter focuses on
- VPLS overview, components, and operation
- VPLS topology – Single PE or direct attachment
- Hierarchical VPLS – Distributed PE architecture
- VPLS configuration and verification
