Configuring super aggregated VLANs
11
Each client connected to the edge device is in its own port-based VLAN. All the clients’ VLANs are
aggregated by the edge device into a single VLAN for connection to the core.
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 24
shows an example application that uses aggregated VLANs. This configuration includes
the client connections shown in
Figure 23
.
FIGURE 24
Example super aggregated VLAN application
Figure 22
shows 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’s
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.
