Hi Gurus,
I have been struggling to get my universal logical switch working , what i have done is the following:
1. The universal switches created from the primary NSX manager have been propagated to secondary NSX manager .
2. After attaching the VM on primary site to the universal switch called USAPP and the VM on secondary site to the same universal switch. The virtual machines are unable to ping each other but the virtual machines on the same site are able to ping each other.
3. Universal Transport Zone, Universal Segment ID has been created as well.
4 VxVLAN has been configured , clusters in the respective site attached
Please can someone guide on where to start troubleshooting or to fix the issue .

Are VTEPs on site A reachable by VTEPs on site B?
What is MTU setting on site interconnect?
You can run checks with following command from site A host:
ping ++netstack=vxlan <site B host VTEP IP address> -s 1572 -d
Please can someone help.

Thanks for your response.
Could you please explain what do you mean by MTU setting on site interconnect?

The recommended MTU size for VXLAN traffic is 1600. All devices through with VXLAN traffic flows, from VTEP to VTEP, should have an MTU of 1600 or greater.
This link proivdes a way to see if connectivity exists among VTEPs from within the logical switch. It does the same command string that yak9 provided, except throught the GUI, and saves you from having to go from host to host to check connectivity.
Also, try restarting the netcpa service on the hosts experiencing issues.
Just wondering, are you using hardware based VTEPs?
and verify the /var/log/netcpa.log - clearly VTEP comms is not okay...

Rather than starting a new thread I'm going to use this old one because I need to understand the correct answer provided to it. I have Cross VC setup but hosts on the same Logical Switch cannot ping each other. The VTEP's on site A are 20.x.x.x/8 and 30.x.x.x/8 on site B. The correct answer suggested those are supposed to be able to ping each other but how would you accomplish that without some kind of router?
Thanks for your thoughts.
Original post and correct answer below for reference.

I added a router between them and it solved the problem.
