What is the function of the Tier-0 Logical Router in NSX-T?

The Tier-0 Logical Router in NSX-T plays a crucial role in enabling communication between virtualized environments and physical infrastructure through dynamic routing protocols. This router is responsible for handling north-south traffic, which refers to the data flows going to and from the data center and external networks. By providing support for dynamic routing protocols such as BGP (Border Gateway Protocol) or OSPF (Open Shortest Path First), the Tier-0 Logical Router facilitates seamless integration with external physical routers, allowing virtualized workloads to interact effectively with outside data networks.

This functionality of the Tier-0 router ensures that the data center can dynamically manage routes and optimize performance for incoming and outgoing traffic, making it essential for an efficient and robust network architecture. The ability to connect to physical routers via dynamic routing sets it apart from other logical routers that may only operate within the virtualized environment or among themselves. Thus, it enhances network flexibility and scalability, crucial for data center operations.
