3.2 Basic VPLS Network Architectures

There are two kinds of VPLS network architectures: PW logical multipoint-to-multipoint
connection architecture and hierarchical architecture. Figure 3-1 depicts a VPLS
network architecture with PW logical multipoint-to-multipoint connection.
Figure 3-1 VPLS network with PW logical multipoint-to-multipoint connection
As shown in Figure 3-1, 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.
Figure 3-2 depicts a hierarchical VPLS network architecture.
