Compatible Systems T1-10/100 manual Frame Relay Dlci Mappings, Required for IP Numbered Interface

Chapter 2 - Quickstart Instructions 8

TB: Use configure and then set the Mode and ConnectMode keywords in the Link Config WAN 0 (and/or any other port you wish to configure) section.

Suggested for Dedicated Line Operation

Dedicated line operation generally does not require additional parameters for operation.

Frame Relay DLCI Mappings

If you are connecting to another Compatible Systems router, this information 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 your WAN interface 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 any other port you wish to configure) section.

IP Protocol

There are two ways to set up Frame Relay. One is to set the WAN interface as a “numbered interface.” This means that the interface (and thus the Frame Relay network) will have an IP address, subnet mask, etc. The other is to set it as an unnumbered interface and specify that the link is point-to-point Frame Relay and set the local DLCI. Unnumbered Frame Relay can only be configured using text-based configuration. Instructions are provided for both options.

Required for IP Numbered Interface

•IP numbered interface

•IP address

•IP subnet mask

•IP broadcast address

CV: Use the TCP/IP Routing: WAN Dialog Box.

TB: Use the configure command and the Numbered, IPAddress, SubnetMask, and IPBroadcast keywords in the IP WAN 0 (and/or any other port you wish to configure) section.

Required for IP Unnumbered Interface

•IP unnumbered interface

•Point-to-Point Frame Relay

•Local DLCI

TB: Use the configure command and the Numbered, PointToPointFrame, and Inter- faceDLCI keywords in the IP WAN 0 (and/or any other port you wish to configure) section.

Suggested for IP

These parameters help supply information about the segment that the interface is connected to. With this information, routing can take place.

•Set IP RIP 1, IP RIP 2, OSPF (Open Shortest Path First) or BGP (Border Gateway Protocol)

•IP static routes

CV: Use the TCP/IP Routing: WAN Dialog Box to set RIP, and the IP Static Routing Dialog
