To further sub-classify each type of traffic by customer, perform one-to-one VLAN mapping on the
wiring-closet switches, and assign a separate VLAN for each type of traffic from each customer. The
required total number of VLANs in the network can be large. To prevent the maximum number of VLANs
from being exceeded on the distribution layer device, perform many-to-one VLAN mapping on the
campus switch to assign the same type of traffic from different customers to the same VLAN.

Application scenario of two-to-two VLAN mapping

Figure 69 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.
