Our present BGP policy states that if a customer has non-portable address space from another upstream ISP, the customer must provide us with an official letter from the owner of the IP address space which authorizes us to re-announce those routes. I feel that this is a reasonable and just policy, but we've been getting quite a bit of flack from customers who claim that nobody else is requiring this.
I am not sure about USA, but it's usial practic here in Russia - we ask e-mail permission from the network owner, and hardly recommend to change address (and warn about _we are doing it at your own risk). The problems are boths political and technical - Internet is not build todays for such _by-specific_ customers and often, if we anounce the specific of the other provider XX, we use partically the bandwidth of XX (esp. if we have peering aggreement with XX).

Are other backbone providers really just announcing whatever their customers ask them to announce? Are we unreasonable in requiring permission to re-announce foreign netblocks? Is there any documentation that sets this down as policy or at least a BCP? Also, is it unreasonable to expect someone who wants to speak BGP to know how to make entries in the RADB, or at least read and follow the instructions? I'm getting the feeling that the latest tech briefings for executives are touting the wonders of BGP, 'cause I'm seeing a lot of pointy-haired bosses demanding it.
