Follow these steps to get your lab started:

Follow the instructions in your lab email to log into the F5 Unified Demo Framework (UDF) where your lab is hosted.

The UDF provides both ssh, TMUI (Web Interface) and a Web Shell access to each component in the lab. No RDP is required for this lab.

For simplicity, its suggested to use the Web Shell in a browser and not the native SSH interface as the latter requires an additional step of setting up ssh keys.
