Re: kern/52439: ipv6 stops routing randomly

Does it make sense that the command "dhcpcd -dB6T --nodhcp6 wm0" on
netbsd8-amd64 and current-amd64 respond differently?

No it does not.

However, dhcpcd-7.0.0-rc2 on a NetBSD-8.99.1 kernel produces output I would expect.

Are you sure it's not a kernel issue? The failing output just shows that dhcpcd sent an RA but didn't receive one.
