By the end of this chapter, you should be able to do the following:
Explain what VPLS stands for
Explain how VPLS emulates an Ethernet switched network over MPLS
When you are able to do these tasks, you will have a thorough understanding of VPLS.
Virtual Private LAN Service (VPLS) emulates a LAN segment across the MPLS backbone across pseudowires or virtual circuits. VPLS creates one or more LANs for each customer who is using the service from the service provider. Each LAN, of course, is completely separate from the other emulated LAN segments—hence the “P” for “Private” in VPLS. When the customer with different Ethernet sites connects to an MPLS backbone where VPLS is ...
