Tunnel endpoints are essential in VMware NSX-T  for managing network connectivity across different environments. They handle the encapsulation and decapsulation of network traffic as it moves between overlay and underlay networks. Here are the key aspects of tunnel endpoints in NSX-T. Its uses in both East-West as well as North-South traffic communication. Geneve Tunneling Protocol : NSX-T uses the Geneve tunneling protocol for encapsulating overlay traffic. Geneve offers a flexible and extensible framework, ensuring efficient and secure communication among virtual machines (VMs) and NSX-T logical networks. Tunnel Endpoint (TEP) IP Addresses: Each hypervisor host or NSX-T Edge node is assigned a unique TEP IP address as its tunnel endpoint. These addresses are used for encapsulating and decapsulating overlay traffic between different endpoints. Overlay Transport Zone (OTZ) : An Overlay Transport Zone defines the scope of network communication within an overlay infrastructure. TEP IP ad
