Autoconfig and RA
http://strugglers.net/~andy/blog/2011/09/04/linux-ipv6-router-advertisements-and-forwarding/
Auto configuration can be disabled temporary for eth1 with:
sudo sysctl -w net.ipv6.conf.eth1.autoconf=0 sudo sysctl -w net.ipv6.conf.eth1.accept_ra=0
or for all interfaces with:
sudo sysctl -w net.ipv6.conf.all.autoconf=0 sudo sysctl -w net.ipv6.conf.all.accept_ra=0
Reenabling works by using 1 instead of 0 in the call.
RADVD
Router ADVertisement Daemon. This daemon listens to router solicitations (RS)
and answers with router advertisement (RA). Furthermore unsolicited RAs are also sent from time to time.
This protocol is meant for host auto-configuration and not for route propagation between routers.
