I stated above that you should not announce another provider's space without their permission, and you specifically agreed. Here you are talking about that space being announced without the owner's knowledge. Make up your mind.

We both agree that announcing another provider's space without their
consent is a Very Bad Thing. I doubt you will find people willing to
post here to the contrary. If the owner _does_ know the space is
being announced, the edge filters are no different whether it is
originated in the second upstream's ASN or an ASN owned by the customer.

So again, I ask, how is that different?

You'll note that you left a word out above. He's agreeing that even if
you do have permission, you shouldn't announce space from another

Type-o's suck. Thanx for pointing it out.

Sorry for the confusion.

Justin, if Provider A _has_ permission from Provider B to announce a prefix, do you believe Provider A should be allowed to announce the prefix?
