How come? Why should RIPv6 work differently over tunnels?
As I see it, tunnel is just an instance of 'normal' point-to-point interface.
The fact that IPv6 packets are encapsulated into IPv4 frames at
link layer should not matter at network layer.  Do you tweak
your network protocols for each meadia it may run over?  I don't.
Here at Bay we have a generic RIPv6 implementation which runs over tunnels
as specified -- the same way it runs over other types of links.

NHRP is not a routing protocol.  Are you proposing to confine 6bone
to a single LIS so no routing would be necessary?
