Currently patching my Proxmox cluster to prep the experimental SDN functionality to enable me to do VXLAN across my cluster of nodes.

I want to test this so I can have virtual routers with devices on the same internal networks but spread across multiple physical nodes.

I'm familiar with doing this on VMware with dVSes and VLANs but trying to replicate it on Proxmox. If this doesn't work as expected I may end up trying some other options. Hope to solve this in software so I don't have to buy gear.

@projectdp wait, it isn't possible now? all bridges are local (to the node) ?

I thought the bridges were local to the node, I don't think they are automatically spanned across your cluster is it?

@projectdp still a one-node-cluster... but thinking about expanding it 😜
So i'm interested in listening your feedback on it 😉

From what I tried previously the bridges are not spanned across the cluster so you do need to implement some other mechanism to have a dvs (distributed virtual switch) equivalent.

What I'm seeing right now after adding the SDN piece is the ability to add Zones and VNets. The VNets will distribute the virtual networks (bridges) to each of the nodes.

Going to try setting this up now!

@projectdp is that on some beta channel? good to hear that they're working on it.

Nope it's available on the non-enterprise repositories but they state in the documentation that it's experimental so there may be some issues with it but I think for lab purposes this is working so far!
