The following diagram shows a four interface router which also supports bridging. Two of the router’s interfaces (Port 0 and Port 1) are set to bridge IP, and two interfaces (Port 1 and Port 2) are also set to bridge IPX.

Bridge Groups on a Multiport Router
The diagram illustrates two Bridge Groups. The IP Bridge Group consists of Port 0 and Port 1. The network segments connected to these two interfaces appear as a single logical segment for IP routing purposes. That is, they will share a single IP network number, subnet mask, and broadcast address. IP communications between these two segments will be bridged, not routed.
The IPX Bridge Group consists of Port 1 and Port 2. The network segments connected to these two interfaces appear as a single logical segment for IPX routing purposes. That is, they will share a single IPX network number. IPX communications between these two segments will be bridged, not routed.
In this example, the segment connected to Port 3 has its own IP network number, subnet mask, and broadcast address. It also has its own IPX network number. Thus all IP and IPX communications between this segment and the two Bridge Groups is routed.
Finally, assuming that
