Dear Colleagues,
The RIPE NCC received the IPv4 address range 82.0.0.0/8 from the
IANA in November 2002. We will begin allocating from this range
in the near future.
You may wish to adjust any filters you have in place accordingly.

Doesn't that argue for a more mesh-like architecture?

Yah, the abstract indicates what most of us already know. Good coverage
and redundancy options in urban areas; less so for rural areas. Why

DRD Doesn't that argue for a more mesh-like architecture?
From a resiliency standpoint, yes. Economics, and to a certain
indirect sense capacity concerns, favor aggregation over route
diversity. N! is not your friend.
Exactly my thought. I didnt mention it for fear of rambling. But
there are areas of limited redundancy, and those are larger targets.

in an endless loop.

I cant see how STP could do this or require that level of DR. Perhaps its just
