Since I’m connecting routers and LANs using ZT I have discovered that blacklisting is needed or ZT will create a feedback loop and storm looking for a better connection to nodes by trying LAN interfaces on the host router. This is unless there is a better way to do this. Presently, this is not well documented save for a few github bug reports.
My request to be a combination of better documentation about this behavior and how the blacklists work, in addition to being able to manipulate blacklists via CLI and API, not just local.conf.
