Ciao Tore, if I am not mistaken this is rather easy and "standard": - Router knows a.b.c.d/x is supposed to be routed via 2001:db::1 - Router can lookup the mac address of 2001:db::1 (usual icmp6) - Router sends packet for a.b.c.d/x towards mac address of 2001:db::1 That's it. Cheers, Nico p.s.: The first few weeks it feels like magic, the following years that method feels like AMAZINGLY USEFUL magic ;-) Tore Anderson <tore@fud.no> writes:

Has anyone implemented lab or production IPv4 next hops over an IPv6 only IX vlan with BIRD as the route server?
I'm interested to hear your experiences. Specifically router vendor interop.
I haven't, but I cannot begin to fathom how that could possibly work.
How can the receiving router possibly resolve an IPv4 next-hop address to an destination Ethernet MAC address, if the interface facing the IX does not have any IPv4 addresses assigned?
What would the next-hop IPv4 address be set to, and how is that determined?
