Symptoms:
- Running the ping command from the control VM of VMware NSX for vSphere 6.x distributed logical router (DLR) to virtual machines connected to internal interface of DLR through a logical switch fails
- The show arp command fails to return the expected table entry for the virtual machines connected to the DLR internal interface.
Environment
