NSXT- 3.0 - Change T0-T1 transit subnets

[Petersaints]

Hi all,

Can anyone help me with this question:

1 - What could happen if i destroy the T0 and create a new one, but instead of leave the T0-T1 transit subnets to be created automatically (100.64.0.0/16), i define a subnet (e.g 100.64.0.0/19)? Will i have any trouble when i need to upgrade nsx-t version? Or will i have trouble in other situations?

Thanks.

Regards.

Hey @Petersaints,

This issue of reconfiguring that network was affecting NSX-T 2.4, however I never changed it so I am not sure if it will affect the upgrade or the communication during the upgrade.

Let me ask you, why do you want to change that subnet?

Hi @Lalegre ,

I did the reconfiguration (delete the actual T0 and create a new one), and it worked fine.

I did that test because probably i will need to use some addresses (managed by me), that i need to be sure that they will not overlap with other addresses.
