When one can't get a base adjacency going, use of further features is 
rather pointless.

But again, it seems those running it on Linux have better luck than 
those on FreeBSD, so that is something to remember. We are a FreeBSD 
house. Our alternative is to use OSPF in Quagga and redistribute it into 
IS-IS. That works well. Would we like to use IS-IS natively? Sure. But 
the alternative has been working well for nearly 10 years.

I think we all appreciate how open source projects work. Calling out 
their limitations is as old as mailing lists. I don't code. I test a 
lot, and continue to test IS-IS in FRR on FreeBSD every year or so. I'll 
keep testing and giving feedback at least once or twice a year. If it's 
still broken, I'll call it out.

Mark.
