Understanding ATM, MPOA, and ATM Router Redundancy Concepts

Figure 1-7. One PVC per Service Record
Assigning one PVC per service record allows you to dedicate a PVC to a
particular protocol, but at the expense of some configuration overhead, memory,
and address space.
This type of configuration is best suited to small, nonmeshed configurations or to
configurations in which protocols must reside on separate PVCs.
Hybrid Access PVCs
PVCs do not typically allow bridging in nonmeshed environments. If your
network combines bridging and routing over the same interface, you need to use
the service record portion of each PVC for routing, while at the same time
allowing bridging to operate. To do this, you must define the PVC as a hybrid/
bridged VC.
Defining the PVC as a hybrid/bridged VC allows the bridge to view each PVC as
a separate bridge interface while allowing the routing protocols to view all PVCs
as part of the same interface (Figure 1-8
).
Note:
The maximum number of PVCs you can configure in this way varies,
depending on the configuration of the router, the number of protocols running
on the circuits, and the number of routing entries.
