Forget theory, I've seen it in practice - it's beautiful 
:-)! The testing we did showed anywhere between 15ms - 25ms 
for reconvergence on a CRS, far better than the industry's 
50ms, and pretty much making the case for the BFD haters.

Of course, real life can throw up a few more surprises, but 
all in all, good promise.

It just doesn't make sense for us when we take the entire 
topology into account, and how infrequent link failures 
cause any major/noticeable issues for service.

YMMV.

Mark.
