Sami,
Here are my configs:
R1:
interface Tunnel1
no ip address
no ip redirects
ipv6 address 2002:C0A8:3C02::2/48
tunnel source FastEthernet0/0.60
tunnel mode ipv6ip 6to4
!
interface FastEthernet0/0.60
ip add 192.168.60.2 255.255.255.0 --------------------------> translate to
C0A8:3C02 in tunnel ipv6 address
ipv6 route 2002::/16 Tunnel1
R2:
!
interface Tunnel1
no ip address
no ip redirects
ipv6 address 2002:C0A8:4601::1/48
tunnel source FastEthernet0/0.70
tunnel mode ipv6ip 6to4
!
interface FastEthernet0/0.70
ip add 192.168.70.1 255.255.255.0 --------------------------> translate to
C0A8:4601 in tunnel ipv6 address
ipv6 route 2002::/16 Tunnel1
HTH,
Srdja

Subject: Re: RIPng over IPv6 6to4 tunnel
Could some one paste configuration of a working 6to 4 Auto tunnel with
multiple sites. I am confused how you map ipv4 address automatically in IPv6
address
Thanks

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,
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.
