How would one deploy a NSX-T overlay network on one host in location A, bridged with an NSX-T overlay network on a different one in location B, while they are on the same vCenter. (or alternative way)

Hi,

Currently the above I have not set up yet, but I'd like to know what my options are of making this work.

I currently have one NSX-T Manager deployed and NSX-T configured on one host, the other host is still untouched. (so the second overlay network has not been made yet.)

What would the best way be to achieve bridging two NSX-T overlay networks together that are on different hosts?

If anyone has ideas on how to do this, please let me know. I have left the remote host untouched and will try what the best option would be to continue with this idea.

The NSX-T version is 3.0 and the hosts are both vSphere 7.

Hi,

Why do you want to bridge ? Do you have a specific reason for this ?

Why not create the transport zone over the 2 hosts ?

Hi,

That is also an option. I just wasn't sure if it was something that would work or not, since the two hosts are in different physical locations. (The management networks of the two hosts are connected together with a VPN). Is that something that would work or that I should at least try?

If the physical locations are separated by public internet, it will have a problem of not being able to run mtu 1600 (which is required)

Maybe it would work with l2-vpn (gre tunnel) or ipsec-vpn. Not sure. Not tested that.

The physical locations are separated by the public internet. That had me worrying because of the MTU, yes. The management LAN on both sides are connected to each other through an IPsec VPN.
