Description of problem: The docker init script does this: preexec="/sbin/sysctl" [ -x $preexec ] || exit 6 $preexec -w net.ipv4.ip_forward=1 > /dev/null 2>&1 $preexec -w net.ipv6.conf.all.forwarding=1 > /dev/null 2>&1 These two settings are not quite equivalent. In particular, net.ipv6.conf.all.forwarding=1 disables autoconfiguration. Version-Release number of selected component (if applicable): 0.7.6-2.el6 How reproducible: Steps to Reproduce: 1. Start with a host using stateless IPV6 networking configuration. 2. Install docker-io. 3. Start docker-io service. Actual results: Loss of ::/0 route (previously auto-configured via a router advertisment). Expected results: No changes in routing table. Additional info: According to Documentation/networking/ip-sysctl.txt setting net.ipv6.conf.xxx.accept_ra to 2 should re-enable it for that interface but that doesn't seem to work for me.
