Configuring super aggregated VLANs
FIGURE 101
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.
