br1 is attached to eno1 (main admin)br10 is attached to eno2 (LXC and apps)br30 is attached to eno2 (LXC and apps)[EDIT 260805 10:00 EST]
Each 30 minutes I am receiving 2 messages from pfSense because br1 is alternating between two MAC adresses:
the MAC from eno2
the MAC attributed to br1
Surely there is something I did not get right while creating my apps and LXC…
Any hint on what to investigate?
You may want to remove eno2 from both bridges. Attach vlan10 to br10, and vlan40 to br40. Have just eno1 attached to br1.
My problem is probably related to this other topic of mine I still have not marked as solved… From Core and Proxmox to Scale | How to properly set the network?
[EDIT]
From what I see on my setup, eno2 is not related directly to br10 or br40
Here are some screenshots to make sure I typed this correctly.
Uncheck “Enable learning” on all bridges. This enables the bridge interfaces into issuing periodic BPDU packets which are causing the behavior you see.
Done. I’ll confirm in ½ hour that it solved the problem.
You’ve got a problem on the switch side propagating BPDUs between VLANs. I’ve only ever seen this with crossed VLANs.
