--- Comment #3 from roy@marples.name ---
Note, this is only an issue if the kernel has received a default router fro=
m a
RA.

So the use case where this fails is the kernel receives a RA from upstream
router and a DHCPv6 client receives a Prefix Delegation from upstream route=
r.
In this case no node on the downstream prefixes will be treated as a valid
neighbour.

The workaround is to disable RA handling in the kernel and let a userland
application (such as dhcpcd) handle it.
