 I was thinking that when I posted yesterday.

These were announcements from a peer, not customer routes.

We are lowering our max prefix limits on many peers as a result of this.

We are also going towards more prefix filtering on peers beyond bogons
and martians.

Hi Mike,

You're not mentioning RPKI here. Any particular reason why not?

If I understand correctly, in today's leak the origin AS was
changed/reset, so RPKI ought to have saved the day. (At least Grzegorz'
day, considering that 33 of AS43996's prefixes are covered by ROAs.)


Yes, we will incorporate RPKI into how we build our prefix filters for
peers as we improve our tools.

Currently this will involve some amount of prefix list compression due to
the limits of current hardware and the need to still have BGP converge.

As Job Snijders said, "I would forsee issues if i'd try to add an eleven
megabyte prefix-list on all devices in the network.".

Mike.


It is NTT that would have mitigated this issue if they deployed and
enforcer rpki, right?
