Advanced Configuration and Management Guide

the flat IP and IPX segment with connectivity to the rest of the network. Within VLAN 4 IP and IPX will follow the STP topology. All other IP sub-nets and IPX networks will be fully routed and have use of all paths at all times during normal operation.

Figure 16.12 shows the configuration described above.
