Client 1 192.168.1.69/24

Path = a single VLAN into which client VLANs are aggregated

Channel = a client VLAN nested inside a Path

sub-net 192.168.1.0/24

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.
