Network design
Appendix B.
considerations
The network examples used in this redbook use IP subnetting. In the example
network used for iSCSI, LAN 1 is subnet zero and the management network is
the all-ones subnet. These two subnets are not differentiable from a full class C
network. The subnet mask for the iSCSI LAN 1 subnet is identical to that of a full
class C network. The broadcast address for the management LAN is also
identical to a full class C network. This can lead to problems in some network
installations with multiple routers.
