Overview of Proxmox SDN Setup

• Introduction to SDN in Proxmox: The video begins by introducing the concept of Software Defined Networks (SDN) in Proxmox, elaborating on its novelty and potential use cases. The presenter mentions the previous videos where Proxmox was installed and container templates were set up.
• Preparatory Steps: Before delving into SDN setup, the presenter underscores the importance of checking system prerequisites through specific commands, ensuring that the system is equipped for SDN implementation. This ensures that viewers are ready to proceed without hiccups during configuration.

Configuring the SDN

• Installing Necessary Packages: The video presents a step-by-step guide on updating the system and installing packages like DNS mask and Frr for routing. The process involves executing commands to disable the default instance of DNS mask and install other essential components to aid in SDN functionality.
• Creating and Applying SDN Components: Detailed instructions are shared on creating the SDN, including setting up zones, vnets, and configuring DHCP settings within the Proxmox environment. The tutorial ensures that even action as complicated as networking is made approachable through systematic guidance.

Finalizing and Testing the SDN Setup

• Launching and Connecting to the SDN: Once the SDN setup is complete, the video shows how to clone a container template and attach it to the newly created SDN. This includes adjusting network settings and ensuring the correct bridge is selected.
• Verification and Conclusion: The final part involves testing the network connectivity to the internet and verifying the correct subnet and IP address assignments. The video concludes with thoughts on potential use cases for SDN in Proxmox and encourages viewer interaction through comments and a blog post.

This structured breakdown ensures viewers can easily follow the complex process of SDN setup in Proxmox from preparation to full implementation and testing.
