IVR Topologies
For IOA to support IVR flows, we recommend that you place the IOA interfaces on the MSM-18/4 or
SSN-16 module in the IVR border switches for optimum routing. IOA must always be deployed on the
host and target VSANs. Packets from the host get redirected to the IOA interface in the host VSAN,
traverses the IVR transit VSANs for routing, and again gets redirected to the IOA interface in the Target
VSAN before it reaches the target and vice-versa. IVR transit VSANs are used only for FC routing. IOA
is not supported or deployed on transit VSANs.
For more information, refer to the Cisco MDS 9000 Family NX-OS Inter-VSAN Routing Configuration
Guide.
