Bug ID: 1065001
           Summary: Starting docker service removes IPv6 default route
           Product: Fedora EPEL
           Version: el6
         Component: docker-io
          Assignee: [e-mail]
          Reporter: [e-mail]
        QA Contact: [e-mail]
                CC: [e-mail], [e-mail],

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.
