As shown in
Each home gateway uses different VLANs to transmit the PC, VoD, and VoIP services.

• To further subclassify each type of traffic by customer, configure one-to-one VLAN mapping on the
wiring-closet switches. This feature assigns a separate VLAN for each type of traffic from each
customer. The required total number of VLANs in the network can be very large.
Application scenario of one-to-two and two-to-two VLAN
mapping
Figure 47 shows a typical application scenario of one-to-two and two-to-two VLAN mapping. In this
scenario, the two remote sites of the same VPN must communicate across two SP networks.

VLAN 3 - > VLAN 301
VLAN 1 - > VLAN 102
VLAN 2 - > VLAN 202
VLAN 3 - > VLAN 302
