200k routes, here we come!
it is just good common sense though, eh?
Well, not necessarily.
Tier-2s should be given much more credit than they typically are in
write-ups like this. When a customer is single homed to a tier-2
that has
multiple tier-1 upstreams, and uses a delegated netblock from the
tier-2's
aggregations, that means one less ASN and one or more less routes
in the
global table.
It's a Good Thing(tm).
For you.
For the customer with an Internet "mission critical app", being tied
to a Tier 2 has it's own set of problems, which might actually be
worse than being tied to a Tier 1.
The Internet is a business tool. If providers do not meet business
requirements, providers will not be supported. Period.
If 200K routes, or more ASNs, or small customers multihoming, or
stuff like that scares you, find another line of work. (Hint-hint to
the v6 fanatics.)
