You create a virtual machine switch on the load balancing failover (LBFO) by using Mellanox NIC adapters.
-
You enable Network Virtualization using Generic Routing Encapsulation (NVGRE) on the LBFO.
In this scenario, the virtual Receive Side Scaling (vRSS) does not work correctly, and the VMQs cannot be created automatically for the teamed adapters. Therefore, NVGRE cannot offload correctly.
