Create the Frame Relay Subinterface

You must create a Frame Relay subinterface for each PVC that you want to
establish through this Frame Relay interface. To create a Frame Relay sub-
interface, enter the following command from the global configuration context
or from the Frame Relay interface configuration mode context:
Syntax: interface frame-relay <number.subinterface number>
Replace the first number in <number.subinterface number> with the number
of the Frame Relay interface that you have already configured. Then replace
subinterface number with any number between 16 to 1007. Using the same
number as the subinterface's DLCI can help you keep track of the subinterface
and troubleshoot any errors.
For example, if your public carrier has assigned your company a DLCI of 16,
enter:
ProCurve(config-fr 1)# interface frame-relay 1.16
You are then moved to the Frame Relay subinterface configuration mode
context, which is reflected in the router prompt:
ProCurve(config-fr 1.16)#
From the Frame Relay subinterface configuration mode context, you can
configure a variety of settings for the connection, including the MTU size and
excess burst rate. However, to initially establish the sublink, you only need to
assign it a DLCI.

Assign a DLCI to the Frame Relay Subinterface

The Frame Relay service provider assigns each PVC endpoint a DLCI on the
Frame Relay switch, and the switch maintains a table of each DLCI so that it
can pass traffic through an outbound port uniquely associated with a specific
peer. Your Frame Relay service provider should tell you the DLCI for the PVC.
To assign the DLCI to the Frame Relay interface, enter the following command
from the Frame Relay subinterface configuration mode context:
Syntax: frame-relay interface-dlci <DLCI>
Replace <DLCI> with a valid DLCI number, ranging from 16 to 1007. You must
assign a different DLCI to each PVC established on the same router.
