Hi Andy,
Thanks for testing, but in the last mail you have sent me, in the config,
these were manual ipv6 tunnels.
Your verification below, was it running over ipv6ip 6to4 tunnels or manual
ipv6ip tunnels? I had no problems to let OSPF run over ipv6ip tunnels but I
could not bring it up with the ipv6ip 6to4 tunnels over frame relay with a
hub and spoke topology. So if the verification below is form the automatic
6to4 tunnels over fr, it would be great to see the config.
regards
Roger

To my experience OSPF won't work over 6to4 tunnels. This is due to
hellos and updates exchange between link-local addresses which one
cannot properly map within 6to4 scheme.(true for RIPng and EIGRP as
well). BGP seems to work though due to TCP nature, but I haven't tried
myself. :-)
Simple static route
ipv6 route 2002::/16 Tunnel NNN
would be a remedy but one has to follow 6to4 rules strictly for IPv^
address assignments. It was a good post about it way back in Dec 08 or
Jan 09.
