You'll be able to ping the IPv4 address but not the IPv6 without the tunnel mode ipv6ip command. Give it a try. Configure the tunnel but don't put tunnel mode ipv6ip and see if you can ping the ipv6 address on the other side of the tunnel. It will fail. The IPv6 route will show as directly connected but since the tunnel doesn't know to encapsulate the IPv6 traffic over IPv4 to send across the tunnel (tunnel mode ipv6ip), your ping will fail. Once you put that in there, you should be able to ping. If you then add your rip commands and debug ipv6 rip, you'll see your rip updates coming across the tunnel.
