Public bug reported: 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.
