While creating a remote gateway on a cloud provider I hadn't used in while, I got sidetracked reading about the services added since last time, specially this BGP service they offer; even if you don't have an ASN of your own, such as it is in the case of a Tunnelbroker range, they can assign a private ASN for you.
I don't know that much about BGP, as much as I try to learn, it fast puts me to sleep, literally. But as I understand provided I have somebody to peer with, I could in theory establish alternate routes than the sole tunnel pathway through which the address space is accessed, correct?
I have zero interest on doing that because the IPv6 space is more useful in my network than it is on a remote firewall that hosts nothing. But I'm still curious, if in the way I think it does, would it work?
One question I got burning in my head is that though they can assign a private ASN, that doesn't negate the fact that the IPv6 range still belongs to an ASN, which I don't have control of, right? As the owner of the range, can HE dictate if additional routes to its space are to be allowed?
Could you break it down in apples and oranges for me? How could alternate routes would, if they could, be established, that is.
Thanks!
