Dumitru, Thanks for your advice. If many clusters connect with each on this way , I am afraid that the ARP flood cant' be controlled. Seems VXLAN EVPN is aimed at this issue ? It's faraway from success now,so I asked advice here. Tian.

Maybe it's because I don't know the whole motivation behind this but wouldn't it be an option to have a single OVN cluster? OVN supports VXLAN encapsulation for non-vtep natively since version 20.09: https://github.com/ovn-org/ovn/commit/b07f1bc3d068e231e40840b0d977bd57158987fd > > Gobpg can act as the MPBGP controller, but I don’t know how to setup > the OVN . > If I understand the requirement correctly, I think having a localnet port on LS-1 (on both clusters) connected to br-vxlan would be enough.
