    i am verry new to the NSX-T technology.

    My question is, does every tenant have its own Overlay network, or is there just one overlay network for all tenants?

    Greetings Tobi

    It all depends upon the design and requirement. For sure there will be multiple overlays for various reasons and some times few tenants will have shared overlay network as well . Since its early stage in the learning process , keep it simple and consider overlay network as pool of network resources with a unique segment ID ( like VLAN ID :smileywink:)  . So in a production environment we will have multiple VLANs and routing might be required for those subnets which are in unique VLAN and that logic is same with NSX integration - Having multiple overlays of which some will be routed and some will demand just L2 connectivity.

    It depends on your network design. You can think of it like VLAN. You can put tenants in 1 VLAN, for example using private VLAN. Or you can have VLANs dedicated for 1 tenant.

    Overlay network is the same concept, the only difference is overlay network is encapsulated to be forwarded through any IP connectivity.
