Introduction

This document illustrates bridging across ISDN using dialer profiles.

The goal of this configuration is to integrate two different IP networks at different locations without using routing. In this document, both routers are configured to dial each other as needed, and IP routing is disabled. IP addresses are configured on the interfaces to manage routers remotely, and for troubleshooting purposes.

Bridging on an ISDN connection tends to keep the connection active for very long periods of time, if not permanently. If your Telco charges for ISDN based on connection time, this can result in a very large bill. Consequently, this scenario is recommended only for those ISDN users who have unlimited-usage ISDN lines.

Note: You may configure the same IP address on both the BRI and Ethernet interfaces of each router. The reason for configuring the IP address is so that you can Telnet to the router for management purposes, or so that you can ping the interface for troubleshooting purposes.

Prerequisites

Requirements

There are no specific prerequisites for this document.

Components Used

The information in this document is based on the software and hardware versions below.

  • Two Cisco 2500 Series Routers, each with at least one ISDN BRI interface

  • Cisco IOS® Software Release 12.2(7b)

The information presented in this document was created from devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If you are working in a live network, ensure that you understand the potential impact of any command before using it.

Related Products

This configuration can be used with any router running Cisco IOS Software as mentioned above, and at least one ISDN BRI port.

Conventions

!--- type values.

!
interface Dialer1 

!--- Configure the dialer profile.

 ip address 10.1.1.2 255.0.0.0

!--- This IP address is for management

Troubleshoot

This section provides information you can use to troubleshoot your configuration.

Troubleshooting Resources

Troubleshooting procedures for incoming and outgoing ISDN calls are explained in Dialup Technology: Troubleshooting Techniques.

Additional information on how to troubleshoot ISDN L1, L2, and L3 issues are given in Using the show isdn status Command for BRI Troubleshooting and Troubleshooting ISDN BRI Layer 3 using the debug isdn q931 Command.

Debug Commands

Certain show commands are supported by the Output Interpreter Tool (registered customers only) , which allows you to view an analysis of show command output.

Note: Before issuing debug commands, please see Important Information on Debug Commands.

  • debug dialer—This command allows you to see when interesting traffic has been detected, and when dialing is initiated.

  • debug isdn event—This command debugs ISDN activity occurring on the user side of the ISDN interface; similar to the debug isdn q931 command.

  • debug isdn q931—This command provides information about call setup and teardown of ISDN network connections (L3) between the local router (user side) and the network.

  • debug isdn q921—This command provides information about data link layer (L2) access procedures that are taking place at the router on the D-channel (LAPD) of its ISDN interface.

  • debug ppp negotiation—This command enables you to review the negotiation of PPP options and Network Control Protocol (NCP) parameters.

  • debug ppp authentication—This command allows you to review the exchange of CHAP and Password Authentication Protocol (PAP) packets.

Before attempting any of the above debug commands, please see Important Information on Debug Commands.
