Yes. I want something redundant, there is a loop somewhere.

I test with STP first, then without: same problem.
I try with link0
"Setting this flag stops all IP multicast packets from being

To prevent the initial broadcast to loop. Does not work...
It a broadcast and not a multicast, after all.

Maybe I need a rule to filter all packet from the oekris itself.
