Set Frame Relay connection
CV:  Use the Link Configuration: WAN Dialog Box.
TB:  Use configure and then set the Mode and ConnectMode keywords in the Link Config 
WAN 0
 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.
Note: 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 window.
TB:  Use configure and set the DLCI keyword in the Frame Relay WAN 0 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 NumberedIPAddressSubnetMask, and 
IPBroadcast keywords in the IP WAN 0 section.
Required for IP Unnumbered Interface
IP unnumbered interface
Point-to-Point Frame Relay
Local DLCI
TB:  Use the configure command and the NumberedPointToPointFrame and Inter-
faceDLCI
 keywords in the IP WAN 0 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
