[c-nsp] Multihoming Question

[Adam Greene]

Paul,

If you have a peering arrangement with the other ISP, I could conceive that 
you could get away with assigning the customer a private ASN which both you 
and the other ISP agree upon. But ... I have never done this. Maybe two 
different private ASNs in this situation (one from each provider) could also 
work, but I expect it would be complicated and I don't see what the 
advantage would be.

Getting a unique public ASN from ARIN is not complicated or that expensive 
($500 setup and $100/yr), and I would expect would simplify things as well 
as put the customer in good stead for the future.

Hope that helps.

Adam
