Roberto, Tony,
Thank you for your responses! I could not find anything like neighbor
statement for RIPng, so I thought that I was missing something here.
Rgds,
Srdja

Subject: Re: RIPng over IPv6 6to4 tunnel
Srdja,
Interesting problem... From you've mentioned I think you already have the
answer... 6to4 tunnels require that they start with a 2002::/16 address
with the IPv4 address embedded in the suffix (so it can determing the IPv4
tunnel destination). With RIPng multicasting it's updates out to neighbors
this won't automatically create the tunnels.
Something to try would be to see if RIPng supports unicast advertisements
(similar to the neighbor statement in EIGRP or RIP for IPv4).
From my experience, all the 6to4 examples I've seen use static routing for
the 2002::/16 address space out the tunnel interface.
