@luckymrwang thanks for looking I guess for yurtmanager is v1.3.4 for gateway version is `raven.openyurt.io/v1beta1`

@luckymrwang could you elaborate about the problems v1beta1 has, or point me to previous discussions about it?

further investigation with `ip -d link show raven0` indicates that, raven0 is marked with nolearning (vxlan attributes learning is false by default). My understanding is flooding traffic is expected behavior?...

Thanks for taking a look. > In the meantime you should be able to explicitly disable segment offloading for the physical NIC in order to mitigate the issue with current...

@jwhited to reproduce: 1. two nodes (linux v6.2) with tailscale (v1.58.2+), with the udp segmentation offloads optimization 2. create a vxlan device on each of them, with tailscale0 being the...

Also seems when there isn't such an error ("error get vxlan parent"...), seems the code path is not triggered and ParentIndex is 0 as well.

ah... I think it's due to our customization, on our edge side, nodes can't talk to each other with their private ip directly; we have to rely on vxlan; that...
