Ahh... that's the part I was missing. Thanks... (All the scenarios I though
of were basically different partial transits...)

Well, _not_ announcing stuff as a rule doesn't break BGP convergence so don't worry about it. :-)

(These Gao and Rexford guys are on to something... I ran their example non-valley-free topology and it was still converging after 15000 iterations.)
