    Please refer the diagram from static VXLANs of AOX-CX VXLAN User Guide. How to setup the network gateways for the host networks? In the virtual interfaces of the two switches?

    Highlighted in RED are the Gateways for the subnets on the switches. The VXLAN interface should be configured with a loopback address (also the address the other switch will use as a Peer Address) for the tunnel creation for VXLAN. See marked up below:

    hi Dustin,

    Thank you for your remind. 

    Since the networks have diffent gateway IP, is the architecture suitable for VM DR?

    As long as both switches 1 and 2 are up and their Vlan interfaces are up, this design will work, but for example if Switch 1 goes down then VMs moved from Network 1 to Network 2 will loose connectivity because they will still try to use 10.0.0.1 (SW1 VLAN10) as default gateway instead of 10.0.0.2 (SW2 VLAN10). Much better solution in this case will be Anycast gateway, e.g. virtual IP address that will be shared by SW1 and SW2 so in this case even if one of the switches goes down the second one will be still available.
