How does NSX-T handle traffic between different segments?

NSX-T utilizes logical routers to manage traffic between different segments within a virtualized environment. Logical routers function as a virtualized routing layer, allowing for efficient inter-segment communication without the need for physical hardware, thus enabling flexible and scalable network designs.

This capability allows NSX-T to route traffic internally between segments that may be isolated from each other while leveraging the robust features of the NSX-T architecture such as distributed routing. This means that routing decisions can be made closer to the source of the traffic, minimizing latency and increasing performance.

While virtual switches play a role in connecting virtual machines within the same segment, they do not handle routing between different segments. Physical routers do exist in traditional network architectures but are not utilized in the NSX-T framework for inter-segment traffic. Direct connections could imply a more manual and less dynamic approach, which does not align with the flexibility and agility that NSX-T provides. The use of logical routers emphasizes NSX-T's capabilities in creating software-defined networks that adapt quickly to changing needs.
