I'm trying to add v6 to my second ISP connection on pppoe1, unlike my
first ISP, this one requires autoconf and dhcpv6-pd to pick up addresses
and have them routed. (They are referring to TR-187,
https://www.broadband-forum.org/technical/download/TR-187.pdf -
the "residential gateway" requirements are in section 6.1)
I haven't got as far as looking at dhcpv6-pd because when I enable
autoconf, as soon as it picks up the address I lose connected routes
to my local /64 subnets:

Anyone have an idea what's going on?
