IPv6 over LANE, you mean?

Sounds to me like once in a while, the router sees an unexpected  
neighbor discovery packet with its own address in it, which I  
speculate could be caused by the broadcast server doing some of its  
emulation magic. It would be useful to tcpdump this to see what's  
going on...

In the mean time, a practical suggestion: if this only happens for  
the global address, and all of this is between a bunch of routers,  
why not forego the global addresses on the LANE cloud and just use  
link locals? IPv6 routers are smart enough to borrow a global address  
from another interface when required and routing protocols only deal  
with link local next hop addresses anyway.
