pTLA rules for application

[info@caladan.net]

I have a question regarding the guidelines for applying for a pTLA 
for the 6bone... 

RFC2772 states that the applicant must have minimum 3 months: 

"Fully maintained, and reliable, BGP4+ peering and connectivity 
between the Applicant's boundary router and the appropriate 
connection point into the 6Bone." 

Surely this breaks one of the golden rules of BGP? i.e. that you 
shouldn't advertise a more specific route when a less specific route 
further up is available? In fact BGP is only really used if you're multi-
homed and you can't be multi-homed on the 6bone unless you're 
already part of the backbone. 

Seems like a chicken and egg situation? 

Perhaps someone could clarify this for me. 

Thanks,
Chris
