> # Configuring Overlay VSANs

> ## Detailed Steps

> To configure an overlay VSAN, follow these steps:

> 1. Add the VSAN to the VSAN database on all switches in the fabric.
> 2. Create a VSAN interface for the VSAN on all switches in the fabric. Any VSAN interface belonging to the VSAN has an IP address in the same subnet. Create a route to the IPFC cloud on the IP side.
> 3. Configure a default route on every switch in the Fibre Channel fabric pointing to the switch that provides NMS access.
> 4. Configure the default gateway (route) and the IPv4 address on switches that point to the NMS
