Chapter 29 Configuring Inter-VSAN Routing Manual IVR Configuration Send documentation comments to [email protected] Step 2 Step 3 Step 4 Click the Action tab. Uncheck the Enable IVR NAT check box (see Figure 29-6). Click the Apply Changes icon to distribute this change to all switches in the fabric. Manually Creating the IVR Topology You must create the IVR topology in every IVR-enabled switch in the fabric if you have not configured IVR topology in auto mode. You can have up to 128 VSANs in an IVR topology. Specify the IVR topology using the following information: • The switch WWNs of the IVR-enabled switches. • A minimum of two VSANs to which the IVR-enabled switch belongs. • The AFID, which distinguishes two VSANs that are logically and physically separate, but have the same VSAN number. You can specify up to 64 AFIDs. See Figure 29-7. Figure 29-7 Example IVR Topology with Non-Unique VSAN IDs Using AFIDs VSAN 10 AF ID 2 VSAN 5 VSAN 10 AF ID 5 IVR-Enabled MDS switch Transit VSAN IVR-Enabled MDS switch 130184 Note If two VSANs in an IVR topology have the same VSAN ID and different AFIDs, they count as two VSANs for the 128-VSAN limit for IVR. Note The use of a single AFID does not allow for segmented VSANs in an inter-VSAN routing topology. Caution You can only configure a maximum of 128 IVR-enabled switches and 128 distinct VSANs in an IVR topology (see the "Database Merge Guidelines" section on page 29-31). To create the IVR topology using Fabric Manager, follow these steps: Step 1 Expand All VSANs and then select IVR in the Logical Domains pane. You see the IVR configuration in the Information pane.
