Re: IPv8 / BGP8 / CF

Let's think about it for a while. There are two ways to transport things in
an ipv8 network.

1. Inside the asn and it's basically ipv4 with a path set so it takes a
lookup to the next ipv4 hop but at the ipv8 router inside the asn it makes
a decision on the ipv4 address destination part and sends it to that
encapsulated address.

So basically the loopback of that ipv8 address.

2. Outside the asn it send it to the ipv4 anycast address.

There are 2 more lookups but the superscalars are not aware of it.

It's not 64 bits of address it's area codes plus address.

So what do you think?
