Compatible Systems 3500R manual Frame Relay Dlci Mappings

Chapter 6 - Basic Configuration Guide 27

Suggested for DECnet

Setting the parameters above should be adequate for most installations.

Frame Relay Configuration

This section covers the settings required for Frame Relay operation of the RISC Router 3500R WAN interfaces. In general, the parameters listed here should be set for each WAN interface on which you plan to use Frame Relay. Note that some WAN interfaces can be running Frame Relay while others are running PPP or SMDS.

The V.35 interfaces can only be run synchronously, at rates up to 2 Mbps per second.

Link Configuration

Frame Relay is presently supported in the RISC Router 3500R only via synchronous 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 (and/or other port numbers you wish to configure) 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 RISC Router 3500R interfaces will be connected to an ISP via Frame Relay, check with your ISP technical staff on whether you must manually enter DLCI information or not.
