Inter-VSAN Routing

IVR is not supported on the Cisco MDS 9124 Fabric Switch, the Cisco MDS 9134 Fabric Switch, the

Cisco Fabric Switch for HP c-Class BladeSystem, and the Cisco Fabric Switch for IBM BladeCenter.

Data traffic is transported between specific initiators and targets on different VSANs without merging

VSANs into a single logical fabric. Fibre Channel control traffic does not flow between VSANs, nor can

initiators access any resource across VSANs other than the designated ones. Valuable resources such as

tape libraries are easily shared across VSANs without compromise.

IVR is in compliance with Fibre Channel standards and incorporates third-party switches, however,

IVR-enabled VSANs may have to be configured in one of the interop modes.

IVR is not limited to VSANs present on a common switch. Routes that traverse one or more VSANs

across multiple switches can be established, if necessary, to establish proper interconnections. IVR used

in conjunction with FCIP provides more efficient business continuity or disaster recovery solutions (see

scenario shown in

Traffic Continuity Using IVR and FCIP

OX ID based load balancing of IVR traffic from IVR- enabled switches is not supported on Generation

1 switching modules. OX ID based load balancing of IVR traffic from a non-IVR MDS switch should

work. Generation 2 switching modules support OX ID based load balancing of IVR traffic from

IVR-enabled switches.
