The version that i want to use is NSX -T 2.4 or 2.5 and the value (Cross vCenter Networking & Security) is not reported in the VMware Knowledge Base , can you help me to clarify this Feature in the version T?
Sorry, I thought it was NSX-V, as Cross vCenter is an NSX-V architecture. NSX-T does support multiple vCenters, but does not have the same concept as NSX-V.
In NSX-T licensing does not mention multiple vCenters, but does mention multiple sites. This is the kb for NSX-T licensing: VMware Knowledge Base
The datasheet also has information regarding licensing and features.
If you want multi-site you need at least NSX Datacenter Advanced.
