VNI pools

actualy in the NSX-Y console I see to places to insert the VNI pools:

1)  systeam > fabric > profiles > configuration

2) network > networking settings > VNI pool

Can  you explain me the purpose of those 2 pools ?

Why inside the 1) we have a  default pool 65536-75000,5000-65535 ?

VNI IDs are assigned to logical switches or segments.  You'll notice the higher numbers are associated with transit and internal segments between components and the lower numbers are user / created segments.

What version? In 3.1 it only exists in the first option.

 

The second option is different in global config and is for EVPN specifically.

VNI Pools

You need to undertake two more preparations for the NSX networks.

The first thing you should do is provide the range or pool of VNIs and multicast groups that NSX Manager would be using for its local use as well as do the same for cross vCenter NSX use. Local VNI pools and universal VNI pools shouldn’t overlap. Local multicast groups and universal multicast groups shouldn’t overlap either. The VNI pool can start at 5000. To create the VNI pools, go to the Segment ID section of the Logical Network Preparation tab and select the Primary NSX Manager. If you require multicast support, you can enter the multicast group pools for NSX Manager to use in the same place.
