VXLan existed issues

[ghost]

Hello, I just encountered the vxlan existed issue when creating topo through meshnet. Any suggestions? Thank you!

This is strange, it's not supposed to happen. How big is your topology? Can you share the topology CRDs?

We are seeing this issue too. It happens randomly on some of our topologies. We've got 2 spines, with 4 leafs connected to each of the spines. We've been getting our fair share of
