Multiple PVCs per service record work best in either fully meshed environments

or in nonmeshed environments where systems not directly connected to each other

have no need to communicate. You can configure multiple PVCs per service

record as long as you do not need to separate protocols by PVC (that is, all PVCs

accept the same protocols).

There are, however, ways to configure upper-layer protocols, such as IP or Internet

Packet Exchange (IPX), to allow systems in nonmeshed networks to fully

communicate. See the documentation for these upper-layer protocols for more

information.

One PVC

One PVC per service record works the same way as multiple PVCs per service

record, except that you assign only one PVC per service record.

This type of configuration is best suited to small, nonmeshed configurations, or to

configurations in which protocols must reside on separate PVCs. When you define

only one PVC per service record, upper-layer protocols treat the ATM network as

a series of direct, point-to-point connections, viewing each PVC as an individual

network interface.

You can, therefore, configure each PVC with different protocols and parameter

settings. This allows you to connect to different network sites using, for example,

different types of data encapsulation (Figure B-4
