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
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.
