Its called MAD, Mutual Assured Destruction.
Even if we discount deliberate sabotoge, mistakes happen. By their
nature, mistakes by large providers are more spectacular. But the
reality is providers of all sizes are one typo away from the dreaded
People can use things like route registeries to match and filter routes
against the registered information. It doesn't really solve the problem,
just moves it to a different place. People can still register annoying
route objects, i.e. the universal default route, and trash connectivity
Its tough to tie particular networks back to valid AS origins since they
are allocated/assigned independently. Worse, if a provider doesn't tell
the rest of us what the valid network/AS combinations are, how will we
ever know when someone announces an invalid network/AS combination. He
who lives by the ANY will one day die by the ANY.
I guess that is what the telephone is for. But when someone blackholes
198.41.0, I hope you have the phone numbers memorized.
