Basic Frame Relay Configuration
North American P850s are configured to have frame relay enabled as
the default setting. With frame relay enabled, the router will
communicate over WAN connections to other frame relay units via
frame relay Permanent Virtual Circuits (PVC). From 1 to 40 PVC’s
may be defined to connect to other frame relay units. Before the P850
can establish a PVC connection to another frame relay router, at least
one PVC must be defined. The P850 is pre-configured to query the
frame relay service to auto-learn the required parameters; they may also
be set manually.
The DLCI (Data Link Connection Identifier) number for the PVC is
assigned by the frame relay service provider. The PVC must be defined
on the physical link on the P850. Refer to the following diagram that
shows three P850 units connected together with a PVC being
configured on each unit. The configuration of the PVCs within the
frame relay cloud is controlled by the frame relay service provider.
