s/routing architecture/business/
It is possible to be a "Tier Two" provider and use communities &
route-maps to look like a Tier One. You purchase transit, therefore
are not tier one, but are unreachable through your transit unless the
end point is a downstream of your transit provider.
Architecturally, those are identical situations. Different
commercial agreements, though.
-- TTFN, patrick P.S. How much you wanna bet some of the "tier ones" are paying other "tier ones" more for fiber or colo or something than the "tier twos".
