thanks for the answer, but it's still a little bit unclear for me.
The gateways are homenet nodes, as node0 is. They're somehow connected
through a babel or olsr network (all of which have to speak hncp I guess?).
Node0 pushes prefixes to node1 and node2 via dhcp.
My main question is how I can configure gateway 0 and 1 to export the
prefixes, and node0 to obtain them.
I'm sorry, I just couldn't yet find any complete documentation yet, but
your example and this:
If there's any docu where all of this is explained, I would be grateful
if you can give me a hint :)
