Bridge problem CCR1072-1G-8S+

RouterOS Beginner Basics

Hello everyone,

recently we bought mikrotik cloud router CCR1072-1G-8S+ and we experiencing some problems with bridge settings on proxmox cluster with Ceph. The router is used as standalone bridge for ceph network. We set it up as bridge, but the problem is, when we connect more than four devices, we lost connectivity to them. First four connectors works ok, but the remaining not. Interesting is, that after reboot, we can ping devices on these ports but after few seconds, the connection is lost. What could be the problem? Thank you for any advice.

Switch off the stp (if no loops can occur) and set administrative mac address to the bridge.

I tried it, and it doesn’t help. Any other ideas? It’s realy wierd, sometimes it works few seconds, another time few minutes.

Which version of ros do you use?

We tried different versions (6.37.4, 6.39.x, 6.41.2 and also 6.42.rc) and the behavior was the same

I am out of ideas. Maybe you can share your exported configuration here and someone could find the reason in it…
