Thank you

Lot depends upon End-End design in the overall datacenter. There is no thumb rule when it comes to multitenancy tenancy , NSX is flexible enough to fit with any designs . For a given

Scenario : Total of 5 tenants and each tenants have 5 VLANS and dedicated routing stack is required however there are few tenants which should be routable between themselves and rest of them doesn't need . In this case VDS design doesn't add much value , unless there is a requirements for VDS features for specific tenants and Uplink connectivity/speed differ across server models which will have a direct impact on tenant design.I hope you got my point. Like I said I would recommend keep VNI completely aside and consider VDS,TransportZone,DLR,Edges etc as the key criteria while designing. Just ensure there are no overlapping Segment-ID while doing cross VC designs.

There is no sub-pool concept in Segment-ID configuration. Either we go with a single pool or if it is a cross VC we will have a universal and Local Pools . Irrespective of the configuration, vni number is a least significant bit in any network and i don't recommend leveraging the number system to align with a specific workloads , for sure values will fluctuate "when  there is a deletion/addition of logical switches", and trying to align VNI that way sounds like traditional VLAN mapping which doesn't add any value in VXLAN overlay network . So you should let NSX take care of the same. Smiley Happy

Many thanks

In this case what would you recommend instead of align VNI for each application or system ? The same question for multi tenant will it be over vDS or Transport zone ?
