Apart from the BGP session itself (which supports multi-AF), the addresses are just needed for resolution of the next-hop layer-2 address. There's no real reason that address needs to be IPv4 and resolved via ARP, it can be resolved just as well with IPv6 ND, as I understand it. For example, on Linux, you can program the FIB in this way: $ ip route add 192.0.2.0/24 via inet6 fe80::1 dev eth0 The 'eth0' interface does not need any IPv4 addresses assigned. Obviously the major router vendors need to build in corresponding capability in their BGP software for IPv6-only IX-es to be a realistic proposition. I have no idea if they have.
