This configuration describes the commands necessary for configuring two 700 Series routers for bridging over ISDN. Notice the IP and IPX networks are the same at both sites. If the networks are different at each site, then a routing configuration would be used instead. The drawback to using a "Bridging" configuration is not being able to use "Dial On Demand" capabilities that would save ISDN line charges.
