Each ESXi host utilizes two physical 10 Gb Ethernet 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 ROBO 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 utilization of the two uplinks of the vDS resulting in better bandwidth utilization and faster recovery from network path failures.

Link aggregation such as LACP between the top-of-rack (ToR) switches and ESXi host must not be configured in order to allow dynamic routing to peer between the ESGs and the upstream switches.
