You appear to have a /64 network address on the inside of your v6 
router. Are you using stateless address auto-configuration? You appear 
to have statically assigned ....::145 as a host address on that net.

My setup works fine if I ping the network address of my v6 router from 
the v6 enabled hosts in my lab.

When you ping local machines on the inside LAN from that router, do you 
see NDP entries being created?

You shouldn't need to use bridging to achieve what you want in this 
scenario, in fact it makes no sense because you want to route v6 traffic 
over the gif, therefore ethernet bridging is not relevant here.
