AIS AI2524 user manual Example Unnumbered IP over a Point-to-Point Subinterface

Chapter 13: AI2524 Frame Relay Configuration Steps

Point-to-Point Subinterfaces

In interface configuration mode, configure transparent bridging for point-to-point subinterfaces:

1.Specify a serial interface. interface serial number

2.Configure Frame Relay encapsulation on the serial interface. encapsulation frame-relay

3.Specify a subinterface.

interface serial number.subinterface-numberpoint-to-point

4.Associate a DLCI with the subinterface. frame-relayinterface-dlcidlci [option]

5.Associate the subinterface with a bridge group. bridge-groupbridge-group

Example: Unnumbered IP over a Point-to-Point

Subinterface

This example sets up unnumbered IP over subinterfaces at both ends of a point-to-point connection. In this example, Router A functions as the DTE, and Router B functions as the DCE. Routers A and B are both attached to Token Ring networks.
