Chapter 12. 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
