What are NSX-T logical routers composed of for routing?

NSX-T logical routers are designed to enable efficient routing within and between virtual networks in a software-defined data center. The correct choice is composed of a combination of Tier-0 and Tier-1 routers, which work together to facilitate different levels of routing.

Tier-0 routers serve as the primary gateway for north-south traffic, connecting the virtual environment to external networks, while Tier-1 routers manage east-west traffic within the data center environment. This hierarchical design allows for greater scalability and flexibility, enabling administrators to create multiple Tier-1 routers under a single Tier-0 router. This separation of routing functions allows for efficient traffic management, improved performance, and streamlined routing policies that can cater to various application needs.

With this architecture, NSX-T can support complex routing scenarios, such as dynamic routing protocols and high-availability features, while maintaining the flexibility required in modern cloud environments. This combination of Tier-0 and Tier-1 routers is essential for providing a robust network infrastructure that facilitates both service chaining and network segmentation.
