Chapter 16 Inter-VSAN Routing Configuration
IVR Zones and IVR Zone Sets
Automatic IVR Zone Creation
Figure 16-3 depicts an IVR zone consisting of four members. To allow pwwn1 to communicate with
pwwn2, they must be in the same zone in VSAN 1, as well as in VSAN 2. If they are not in the same
zone, then the hard-zoning ACL entries will prohibit pwwn1 from communicating with pwwn2.
A zone corresponding to each active IVR zone is automatically created in each edge VSAN specified in
the active IVR zone. All pWWNs in the IVR zone are members of these zones in each VSAN.
Figure 16-3 Creating Zones upon IVR Zone Activation
The zones are created automatically by the IVR process when an IVR zone set is activated. They are not
stored in a full zone set database and are lost when the switch reboots or when a new zone set is activated.
The IVR feature monitors these events and adds the zones corresponding to the active IVR zone set
configuration when a new zone set is activated. Like zone sets, IVR zone sets are also activated
nondisruptively.
Note If pwwn1 and pwwn2 are in an IVR zone in the current as well as the new IVR zone set , then activation
of the new IVR zone set does not cause any traffic disruption between them.
IVR zone and IVR zone set names are restricted to 64 alphanumeric characters.
Configuring IVR Zones and Zone Sets
To create IVR zones or zone sets using Fabric Manager, follow these steps:
Step 1 Select the VSAN that you want to configure from the Logical Domains tree.
Step 2 Choose Zone > IVR > Edit Local Full Zone Database from the Zone menu.
