Powershell: VMware NSX duplicate VTEP addresses
Roughly a half year ago we came across a situation in which an VMware NSX environment was having problems consistingly applying routing and firewall rules. After some troubleshooting it appeared to be a problem with duplicate VTEP (VXLAN Tunnel Enpoint) addresses on the vSphere hosts. We fixed the problem, but we wanted to have some sort of periodic check to alert us, should this occur again.
