At this stage, we have covered components of virtual networks within the Proxmox cluster environment. We know the components Proxmox uses to hold everything together.
We are going to take a look at a few virtual environment scenarios to solidify our understanding of networking in a Proxmox virtual environment. These are scenario-based network diagrams and some of them are taken from a real production environment.
This is a small-scale Proxmox cluster with three nodes and two subnets within the virtual environment. Each Proxmox node has two NICs, and both the bridges vmbr0 and vmbr1 are attached to eth0 and eth1, respectively. Each bridge has three virtual machines attached to it. Outside the virtual environment, there is a physical switch, which connects Proxmox nodes, and an admin console for all management work. This is Proxmox in its simplest form in a production environment. This type of network can be used as a learning...
