To further sub-classify each type of traffic by customer:
Perform one-to-one VLAN mapping on the wiring-closet switches.

Assign a separate VLAN for each type of traffic from each customer.

The required total number of VLANs in the network can exceed the maximum number of VLANs on the
distribution layer device. To prevent this:
 Perform many-to-one VLAN mapping on the campus switch.
 Assign the same type of traffic from different customers to the same VLAN.

Figure 56 shows a typical application scenario in which two remote sites of VPN A, Site 1 and Site 2,
must communicate across two SP networks, SP 1 and SP 2.
