Frame Relay Configuration
This section covers the settings required for Frame Relay operation of
theMicroRouter 1200i WAN interfaces. In general, the parameters

use Frame Relay.
Link Configuration
FrameRelay is presently supported in the MicroRouter 1200i only via
dedicated line operation.

Dedicatedli ne operationgenerally does notrequire additional parame-
tersfor operation.

Frame Relay DLCI Mappings

Ifyou are connecting to another Compatible Systems router, this infor-
mationis n ot required for Frame Relay operation. Compatible Systems
usesIARP (InverseAddress Resolution Protocol) to dynamically
generate this information. Toconnect to other vendors’ r outers which
do not support IARP,y ou must provide DLCI-to-protocol mapping
information.
Note: ManyInternet Service Providers (ISP’s)do not support IARP
asa default. If one of your MicroRouter 1200i interfaces will be
connectedto an ISP via FrameRelay, check with your ISP technical
staffon whether or not you must manually enter DLCI information.
CV: Usethe DLCI Mapping Database Dialog Box (under WAN>Link
Configuration>DLCIbutton).
TB: Use configure and set the DLCI keyword in the Frame Relay
WAN 0 (and/or WAN1) section.
