[Launchpad Bug Tracker <886410@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

On my network, I broadcast additional routes via IPv6 RAs. These routes
do not appear to be picked up by the kernel, even though
/proc/sys/net/ipv6/conf/all/accept_ra_rtr_pref is set to '1'

I ran into this issue because I'm also using gogoc to give my laptop a
globally unique IPv6 address that's valid even when my laptop isn't on
my home network. My home network has a /48 (divided into two /64s) a
distinct /64.

As soon as the gogoc client comes up, all traffic, even to my own IPv6
subnets, tries going out through gogoc--I got blocked by my own
firewall, because my traffic had the appearance of coming from outside.
(Well, it was; it was likely bouncing off of New York or Amsterdam
before it got back to me)

To solve this problem, I specifically noted my network's /48 and
distinct /64 in my RAs, but they were nowhere to be found in my
laptop's routing table.

I thought this was a NetworkManager issue at first, but I walked through
it with dbcw in #nm on Freenode, and this is where I wind up. I'll
attach radvd.conf, a stretch of syslog showing the connection and
disconnection from the network, and the conversation from #nm.
