To start, I was thinking of the following topology:
- two 'backbone-node' where we pull in the tunnels from the 6bone. (two
nodes, for redundancy)
- From those 'backbone-nodes', tunnels towards the 'internal' networks.

I would like to use both cisco-routers and unix-routers for this.

So, I guess I have two options: RIPng and BGP.
(I'll try both to see what turns out to be best).

Euh ... what is a 'Ships-In-the-Night argument' ??? (what does this mean?)

Well, I would use my backbone-AS on the 'backbone-nodes', but private
ASnumber on the 'internal networks'. In that case, there is no need for a
full-BGP-mesh.

Cheerio! Kr. Bonne.
