Figure 16.16 Conceptual Model of the Super Aggregated VLAN Application
Each client connected to the edge device is in its own port-based VLAN, which is like an ATM channel. All the
clients’ VLANs are aggregated by the edge device into a single VLAN for connection to the core. The single VLAN
that aggregates the clients’ VLANs is like an ATM path.
The device that aggregates the VLANs forwards the aggregated VLAN traffic through the core. The core can
consist of multiple devices that forward the aggregated VLAN traffic. The edge device at the other end of the core
separates the aggregated VLANs into the individual client VLANs before forwarding the traffic. The edge devices
forward the individual client traffic to the clients. For the clients’ perspective, the channel is a direct point-to-point
link.
Figure 16.17 shows an example application that uses aggregated VLANs. This configuration includes the client
connections shown in Figure 16.16.
