Time has passed, and I'm now running netbsd-9 on the orange pi, and
on the amd64 router. I still see these issues with IPv6 route flaps.
From the arm side:
Mar 9 20:52:20 thing1 dhcpcd: emac0: Router Advertisement from fe80::52e5:49ff:fea6:f5d8
Mar 9 20:52:20 thing1 dhcpcd: emac0: fe80::52e5:49ff:fea6:f5d8: no longer a default router
Well, that's pretty telling.
dhcpcd received a RA with a router lifetime of zero.
It's not that the route is flapping, it's the router saying it's no longer a
default router and should not be used.
dhcpcd is just doing what it's told.
The rest of the debug is irrelevant at this point.
Is there anything on your router restarting rtadvd as that would trigger the above?
