Argues that by going from a dual-router POP design to a
single redundant router configuration, I can reduce annual
downtime costs by 93% (?) and reduce CAPEX and OPEX (seems
logical).

Also mentions that the single redundant router can get
closer to the ever-elusive 5-9's.

Anyone doing this in their network? Is there validity in the
claims in this white paper? Anyone looked at the Alcatel
product that apparently funded this paper?

I'd believe the numbers in this, what I don't believe yet
though is that there are products available that true give
the same level of redundancy that having two boxes does...

Neil.
