Re: General question on rfc1918

Hi there, I just had a real quick question. I hope this is found to be on topic.
You should not send packets with RFC1918 source or destination addresses to the Internet. Everybody should follow this advice. If everybody did follow that advice, you wouldn't see the packets you are seeing.
The cynical answer, however, based on observation of real-life networks, is "yes" because people are naturally messy creatures.
We have filters in place on our edge (obviously) but should we be seeing traffic from 192.168.0.0 and 10.0.0.0 et cetera hitting our transit interfaces?
I can think of lots of things that large carrier networks (as well as smaller, non-carrier networks!) do that seem on the face of it to defy explanation, of which this is just one example :-)
