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
