Configuring super aggregated VLANs
FIGURE 49 Example of a super aggregated VLAN application
In this example, a collocation service provides private channels for multiple clients. Although the
same devices are used for all the clients, the VLANs ensure that each client receives its own Layer
2 broadcast domain, separate from the broadcast domains of other clients. For example, client 1
cannot ping client 5.
The clients at each end of a channel appear to each other to be directly connected and thus can be
on the same subnet and use network services that require connection to the same subnet. In this
example, client 1 is in subnet 192.168.1.0/24 and so is the device at the other end of client 1
channel.
Since each VLAN configured on the core devices is an aggregate of multiple client VLANs, the
aggregated VLANs greatly increase the number of clients a core device can accommodate.
