Five years ago there wasn't a single IP router capable of doing OC48 either.

How do we fix this?

1) Convince large/tier 1 peers to include full route table filter requirements
in their purchasing when deciding whether to buy Cisco or Juniper?

2) Pass the Internet Stability Act of 2000 mandating full peer filters by
2002, and providing for civil fines by any affected party against any tier
one not in compliance?  Any router vendor not in compliance will be removed
from the GSA purchasing schedule.


This is a very old problem folks.  We've known about several solutions for years.
