I can start an instance that is available across the cluster(the same security group).
But, it seems to be happening on the network loop tunnel interface between clusters.

Two ClusterContoller (CC01, CC02) in the environment, CC02 following error message is logged in /var/log/messages

Dec 22 12:49:50 dev-cc02 kernel: tap-0-1.10: received packet with own address as source address
Dec 22 12:50:50 dev-cc02 kernel: tap-0-1.10: received packet with own address as source address

Dec 22 12:58:50 dev-cc02 last message repeated 2 times

What are the problems of multi-cluster configuration errors and network design?
I would like to ask for your advice.

Detailed logs and configuration information, please see below.

→ It seems that it occures by the broadcast network loop in CCs tunnel.
I think that the mac address duplication is detected so.
