Each ESXi host uses two physical 10-GbE adapters, associated with the uplinks on the vSphere Distributed Switches to which it is connected. Each uplink is connected to a different top-of-rack switch to mitigate the impact of a single top-of-rack switch failure and to provide two paths in and out of the SDDC.

ROBO-VI-SDN-007

Set up VXLAN Tunnel Endpoints (VTEPs) to use Route based on SRC-ID for teaming and failover configuration.

Allows for the use of the two uplinks of the distributed switch resulting in better bandwidth utilization and faster recovery from network path failures.

None.
