Everyone who posted in this thread was well aware of that.  (Well, except me in my first post. :)  Google was still the victim, and it was still not their fault.

You are showing wide and clear ignorance on the basics of peering.  Which is fine, the vast majority of the planet hasn't a clue what peering is.  However, the rest of the people who do not know what they are talking about have managed to avoid commenting on the subject to 10K+ of their not-so-closest friends.

To be clear, if you had started with something like: "Why is Google originating the route?  Doesn't that make it valid?", you would have gotten a lot of help & support.  But instead you started by claiming it was Google's fault and they could stop this by setting "the correct BGP attributes".  I note you still haven't told us what those attributes would be despite repeated questions.

Perhaps it's time to admit you don't know what attributes, and you need a little more education on peering in general?

When you find yourself in a hole, stop digging.
