In Figure 55, the network is planned as follows:
Each home gateway uses different VLANs to transmit the PC, VoD, and VoIP services.
•
To further sub-classify each type of traffic by customer, configure one-to-one VLAN mapping on the
•
wiring-closet switches. This feature assigns a separate VLAN to each type of traffic from each
customer. The required total number of VLANs in the network can be very large.
• To prevent the maximum number of VLANs from being exceeded on the distribution layer device,
configure many-to-one VLAN mapping on the campus switch. This feature assigns the same VLAN
to the same type of traffic from different customers.
