Cool. Statically defining the local-link addresses would seem prudent. I
will do so in the future.
I've used the following protocols over v4 tunnels.
NAT-PT v4v6, v6v4 <---good
MP BGP IPV6 <---good
RIPng <---good
ISIS <--- can't seem to get it run over a tunnel
OSPFv3 <---haven't tried
TIA

Alsontra,
I have found that link-local addresses combined with the neighbor
discovery process (ICMP) in IPv6 is the equivalent of ARP in IPv4.
Basically you don't have ARP for IPv6. Instead you get the combined
action of neighbor discovery and link-local addresses.
It is my opinion when you look at NBMA interfaces for IPv6, that you
statically set the link-local address so that the remote router doesn't
change it on you after a reboot (remember that the link-local address
setting procedure is dynamic to a device). And, since frame relay
interfaces/serial/atm don't have a mac address associated with them,
they will have to take one from the local router pool thereby meaning it
could change. And statically mapping link-local addresses on one end
that can change on the other is a bad idea and something I think you
might be enticed to do in a lab environment.
My 2cents.
Anyone had any luck with the various IPv6 over ipv4 tunneling
technologies and running IGPs across them?

Subject: IPV6 Recursive Routing - ATM FRAME ISDN?
All
When IPv6 is configured on a frame-relay interface the address is
recursively resolved to the local-link address of the serial interface.
I'm finding that it's almost always necessary to map the local link
address. Is this the case with all media requiring L2 resolution?
How does ATM handle this type of behavior?
TIA
