Frame Relay Configuration
This section covers the settings required for Frame Relay operation of
the MicroRouter 2220R WAN interfaces. In general, the parameters
listed here should be set for each WAN interface on which you plan to
use Frame Relay.
Link Configuration
Frame Relay is presently supported in the MicroRouter 2220R only via
dedicated line operation.

Set Dedicated connection

Set Frame Relay connection
CV: Use the Link Configuration: WAN Dialog Box.
TB: Use configure to set the Mode and ConnectMode keywords in
the Link Config WAN 0 (and/or WAN 1) section.
Suggested for Dedicated/Leased Line Operation
Dedicated line operation generally does not require additional parame-
ters for operation.
Frame Relay DLCI Mappings
If you are connecting to another Compatible Systems router, this infor-
mation is not required for Frame Relay operation. Compatible Systems
uses IARP (Inverse Address Resolution Protocol) to dynamically
generate this information. To connect to other vendors’ routers which
do not support IARP, you must provide DLCI-to-protocol mapping
information.
v
Note:
Many Internet Service Providers (ISP’s) do not support IARP
as a default. If one of your MicroRouter 2220R interfaces will be
connected to an ISP via Frame Relay, check with your ISP technical
staff on whether or not you must manually enter DLCI information.
CV: Use the DLCI Mapping Database Dialog Box (under WAN>Link
Configuration>DLCI button).
TB: Use configure and set the DLCI keyword in the Frame Relay
WAN 0 (and/or WAN 1) section.
