  despite absence of security group rule allowing so. V4 traffic is
  blocked.

  Build: Master Nov. 11/11/15
  Setup: One controller/Network node, Two Compute nodes.

  Steps:
  1. create net1 and net2.
  2. create IPv4 and IPv6 subnet(slaac/slaac*) on each network.
  3. create DVR.
  4. Add router interface for each of four subnets to DVR.
  5. Boot instance with nic on net1 and other with nic on net2.
  6. Delete all security group rules if any exists.
  7. Ping6 v6 IP from one instance to the other.

  Expected: Traffic does not go through.
  Observed: Traffic goes through.

  *also observed with dhcpv6-stateful addressing.
