Yep, unbelievable the ammount of work you put into trying to disqualify
something using psychology tricks. But I'm keeping it technical now,
sort of :-)
Many algorithms do use a try and get better "iterative" way of reaching
target, may be I'm using that!

BTW, I don't know how "R1 - FRsw - R2" is perceived by you as a new
topology, may be you have a different semantics for topology.

And you hoped it would work ? Didn't I say that the frame switch would
drop it if one end had LMI configured and up ?

I'm glad you now see it, it's been 3 or 4 mails ago when I mentioned it.

Right, also mentioned by me some time ago. Glad you learned something too.

Enough of this already. Agreed.
