N-S traffic via DLR in NSX-T

[MRoushdy]

Hello,

My background is focused on NSX-V, and now I'm studying NSX-T. I am confused about something, I've deployed NSX-T in my lab, and everything seems healthy, but, I wan't to configure a "Tier-0" gateway using a DLR as in NSX-V without leveraging an edge node, I don't want to use an edge node in this scenario, so I just want a DLR to perform both east-west, and North-South routing. is this doable?

To my knowledge, no, all N/S traffic passes through the edge cluster, which can be in A/A or A/S mode.

N/S is always done via the Edge, either in NSX-v or NSX-T. What you can do in NSX-T is use a single tier routing design where both N/S and E/W is done by the T0. In this case E/W will be distributed and only N/S or any stateful services like load balancing and NAT would go through the Edge using the T0 SR. This concept is quite different that it is in NSX-V.

Take a look at these posts that explain very well NSX-T routing architecture:
