4. Enable routing modules to use the interface.
1. Create the Frame Relay interface
To create and associate the Frame Relay interface with a synchronous
interface or an ISDN call, enter the command:
create fr=n over=physical-interface
where n is the number of the Frame Relay interface and physical-interface is
a synchronous interface such as “syn0” or an ISDN call such as “isdn-Head
Office”.
To display each Frame Relay interface, the physical interface it uses, and
the logical interfaces it provides, enter the command:
show framerelay
A feature of Frame Relay is the dialogue that the network maintains with
the devices connected to it. This dialogue is known as the Local
Management Interface (LMI). A LMI is not provided by all Frame Relay
networks. Your router supports Frame Relay networks that do not run the
LMI by allowing the configuration of static Data Link Connections (DLCs).
Parameters that affect the LMI dialogue are also set with the CREATE
command. These parameters, and the values that they can take, are defined
in the Frame Relay standards. Default values for the LMI parameters are
defined in the standards, and are used when parameters are not supplied.
Consult your Frame Relay network provider before making changes to the
parameters that affect the LMI dialogue.
Parameters for setting the interface defaults for encryption and
compression are also set with the CREATE command. These values are
used by all DLCs on the interface unless specifically overridden for a
particular DLC.
After the Frame Relay interface is created, to change the LMI parameters,
enter the command:
set framerelay
You may modify any or all of the parameters on a single command line.
However, only ENCAPSULATION, NT1, NN1, NN2 and NN3 parameter
changes take effect immediately. All other parameter changes cause the
Frame Relay interface to reset automatically before they take effect.
To display the current values of the parameters, enter the command:
show framerelay config
2. Add static DLCs if required
If the LMI dialogue is turned off for a Frame Relay interface, the router is
not informed about active DLCs. Therefore you must set up static DLCs. To
set up static DLCs, enter the command:
add framerelay=fr-interface dlc=dlci
[compression={default|on|off}]
[encapsulation={default|ietf|cisco}]
[encryption={default|on|off}]
To remove static DLCs, enter the command:
delete framerelay dlc
If no encryption or compression parameters are specified when the DLC is
added, the interface defaults, which are set via the DEFENCRYPTION and
