operation when you are connecting to another Compatible Systems router at the other end of the link.

Frame Relay Configuration

This section covers the settings required for Frame Relay operation of the MicroRouter 900i 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 900i only via dedicated line operation.

•Set Dedicated connection

•Set Frame Relay connection

CV: Use the Link Configuration: WAN 0 Dialog Box.

TB: Use configure to set the Mode and ConnectMode keywords in the Link Config WAN 0 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.

ϖNote: Many Internet Service Providers (ISP’s) do not support IARP as a default. If one of your MicroRouter 900i interfaces will be connected to an ISP via Frame Relay, check with your ISP technical staff on whether you must manually enter DLCI information.

CV: Use the DLCI Mapping Database Dialog Box. (Use WAN 0/Link Configuration, select Frame Relay Link from the Link Type pull-down menu, and click on DLCI button.)
