Hi all :)

Im trying to set up proxmox to be able to use routed network instead of bridged.
My routers are currently running bgp and pushing different nets thru ospf and on the nodes themself i have a software called bird running to handle and route the ospf network and routes so its available on everynode.

However it seems like its only possible to put the vms in a bridge, unfortunately my setup dont work there as the interfaces (tap100i0) are attached to the vmbr0 bridge.

Is there anyway to use or apply this type of routing while using proxmox?

id rather not put all the subnets in vlans and have it broadcasted to my whole environment as i would have to create shitloads of firewall rules and put all ips and smaller nets in vlans.

Hi,
I'm not sure it could feed your needs, but proxmox have a beta sdn feature
https://pve.proxmox.com/pve-docs/chapter-pvesdn.html

currently support bgp-evpn for vm vxlan routing. It's using frr router currently.
(I don't have any ospf support currently, only i-bgp e-bgp).

If you router don't support evpn, it's possible to use some proxmox nodes as exit-gateway for vxlan traffic, using classic routing up to your bgp routers.
