Universal Transport Zone with Cross vCenter NSX

Site A and B environment:

     vCenter Server:6.0

     NSX for vSphere:6.3.5

     primary NSX Manager on Site A,secondary NSX Manager on Site B

Site A and Site B each have vCenter and NSX deployed. NSX Manager of site A is the primary role,and site B‘s is the secondary role.

Host Preparation、VxLAN Transport are complete configuration at both site A and B,and I set Universal Segment ID Pool and Universal Transport Zone only on the primary NSX.

On secondary NSX,the Universal Segment ID Pool configuration has been synchronized from primary NSX, but the Universal Transport Zone was not  synchronized.

So,I go back to Installation/Management,press on Actions on top of NSX Manager,and choose  Perform Universal Synchronization and press Yes,the Primary NSX Manager shows that is Replication in process and lasts for a long time。However,the Secondary NSX still does not appear Universal Transport Zone.

The Universal TransportZone sync info in the primary NSX Manager  is :

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.

Thanks for your reply!

But in the secondary NSX the TransportZone list  is empty and there is no Universal TransportZone. Also,the secondary NSX cannot manually create a Universal TZ,only the Global TZ.

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???).
