In a typical triple-play network configuration over Ethernet, individual subscribers
are represented on the B-RAS by VLANs and DSLAMs by SVLANs. Figure 19 on
page 81 illustrates how to shape the subscriber aggregate of voice, video, and data
to a single rate in Ethernet.

Configuring Simple Shared Shaping
This section explains how to configure the shared shaper by specifying a
shared-shaping rate for either the best-effort queue or the best-effort scheduler node
for the logical interface. The router locates the other queues associated with the
logical interface and shapes that set of queues to the shared rate.
You do not explicitly specify shared shaping on the other queues for the logical
interface. You can configure individual shaping rates on the other queues that are
less than the shared rate. These individual shapers have the effect of reserving some
of the shared bandwidth for the other queues.
