Or don’t use a route server except to bootstrap.  I regularly see issues related to them.  I get it’s not easy to peer at an IXP, but IXP peering isn’t for everyone as some people might make it sound.  This is why back in the day there was a push to require 24x7 staffing of the remote side to ensure it was being monitored/supported.

That may no longer apply to many people, but without active monitoring, you won’t know what the state is of the remote side.
