Once the universal sync is done, you still need to manually add the clusters you want under the site B vcenter/NSX Manager to the universal transport zone before universal objects will get synchronized to them.  Procedure is described in the Add Clusters to the Universal Transport Zone section of the admin guide.

Hi Silen

MTU from SiteA to SiteB is 1600 or more??

What about "vmkping ++netstack=vxlan -s 1570 ...." from an Host of SiteA to an Host of SiteB ... to test VXLAN reachability ??

Regards,

Lorenzo

If you go to the system events (Networking & Security > System > Events) what does it show after the sync fails?

Hi,

in my previous question of reachability was implied also that on the secondary site everything is working fine... (VTEPs and all components concerning Host Preparation are correctly installed and license as well, on both sites) :-)

So, have you tried to create a Local Transport Zone on secondary NSX Manager?? Works fine?? if yes the problem is in the middle (MTU, ports ect Ports and Protocols Required by NSX  ) if not the problem could be somewhere else (i.e. NSX Universal Synchronization Service are running correctly???).

Have you seen also this Replication - Universal Sync System Events ??

I forgot to ask ..... obviously, the Controllers have been correctly deployed?

Hi Silen,

please clarify us if:

1 - Ports between sites are open??

2 - MTU  between sites is, as required??
