Hmm, why would a router forward L2 broadcast packets though (in your case they're not ARPs as the logs in your gist showed)? In any case, would it be possible to patch the OVN version you're running and revert https://github.com/ovn-org/ovn/commit/325c7b203d8bfd12bc1285ad11390c1a55cd6717 ? > > > >> On 3/3/25 3:53 PM, support wrote: >> > Sorry for mispelling Dumitru!
