In this sample configuration, MP Router 1 must have a GbE connection to IP subnet A and a GbE
connection to a IP subnet B. A Fibre Channel host or device connected to Fabric 1 can access
devices in Fabric 2 and/or Fabric 3.
Figure 120 (page 294) shows a redundant FCIP configuration in which pairs of MP Routers provide
full redundancy. Loss of an MP Router or loss of connectivity through one of the IP networks does
not disrupt the fabric connections.

C-series MDS 9216i, 9222i, IPS-4, IPS-8, 14/2 Multiprotocol Services Modules,
18/4 Multiservice Modules
The C-series MDS 9216i, MDS 9222i, IP Storage Services Modules (IPS-4, IPS-8), 14/2
Multiprotocol Services Modules, and 18/4 Multiservice Modules provide MDS FCIP and iSCSI
functionality.
The IPS-4, IPS-8, 14/2, and 18/4 modules integrate seamlessly into the C-series MDS 9000
switches and support the full range of features, including VSANs, security, and traffic management.
You can use the C-series modules in the C-series SN8000C, 9500 and 9200 series switches. The
IPS-4, IPS-8, 14/2, and 18/4 modules have four, eight, two, and four 1 Gb/s Ethernet ports,
respectively.
