There are two kinds of VPLS network architectures: PW logical
multipoint-to-multipoint connection architecture and hierarchical architecture.
Figure 152 depicts a VPLS network architecture with PW logical
multipoint-to-multipoint connection.

Figure 152 VPLS network with PW logical multipoint-to-multipoint connection
As shown in Figure 152, VPLS can provide point-to-multipoint connection service
like a L3VPN. It can learn MAC addresses and exchange packets between multiple
sites. In addition, it keeps the forwarding tables of the individual VPNs
independent with each other and allows MAC address overlap between VPNs.
