 Description   

When creating tunnels ports on an OVS bridge with more than one OVS connected, the tunnel port gets replicated on all other switches. We first the issue in Netvirt CSIT like [1].

This can be easily reporduced with genius, by creating a transport zone with two DPNs, which result in 2 tunnels created on both when it should be one tunnel on each. here is a sample output:
