Hi v024302,
[… bond, bridges, dummy interfaces, IPs …]
But the [dummy] Interfaces just can ping their own IP.
one of my favorite areas of problems, which I know exists but I cannot explain (didn’t yet have the time to dig into the depths): From my experience, once you’ve set an IP address to the bond interface, you run into trouble if you unset the IP and re-set it at a higher layer (i.e. the bridge or the dummy interface). I even had a case where only setting 0.0.0.0 for the bond interface already caused this.
Have you restarted your server after changing the config to your target setup (bond0 via the two physicals, bridge connecting to bond0, two interfaces connecting to the bridge, each with its respective IP address)? If not, I suggest to give it a try. Do not touch the IP config of bond0 or the bridge device - if you created the bond via YaST, don’t give it an IP address at all. Once the dummy adapters have their IPs, try to ping again.
Regards,
J
