26 Chapter 6 - Basic Configuration Guide
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.
Note: Many Internet Service Providers (ISP’s) do not support IARP
as a default. If one of your MicroRouter 1250i 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.
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.
IP Protocol
There are two ways to set up Frame Relay. One is to set the WAN inter-
face 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.
Required for IP Numbered Interface
• IP numbered interface
•IPaddress
• 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,andIPBroadcast keywords in the IP WAN 0
(and/or WAN 1) section.
