Figure 2-6 Topology of a service provider network
Figure 2-6 shows the network topology of the service provider network:
z The S7500 switches (Switch A, Switch B, and Switch C in the network diagram)
operate as the edge devices of the service provider network and are connected to
server-side or client-side networks.
z The service provider network permits the packets of VLAN 100 and VLAN 200 to
pass through.
z Switch B is connected to the service provider network through GigabitEthernet
2/0/2, which permits the packets of VLAN 100 to pass through.
z Switch C is connected to the service provider network through GigabitEthernet
2/0/2, which permits the packets of VLAN 200 to pass through.
