Description of problem: It's possible there is no connectivity between two VMs on different subnets and different computes, as long as the subnets were created after one of the vms was started. After talking to Sridhar and Aswin, it seems that it's an sg related issue. How reproducible: 100% Steps to Reproduce: 1. Create a network, ipv4 subnet and router 2. Start a VM on this subnet 3. Create an additional ipv6 subnet on the same network and create another network and subnet with ipv6 and ipv4 4. Add these 3 new subnets to the router 5. Start a VM on a different compute 6. Try to reach the new vm from the old one on ipv6 Actual results: There is no connectivity. Although both vms have ipv6 addresses assigned and connectivity on ipv4 works as expected.
Retargeted to OSP13 z4 since we want that fix there (will cross tag to OSP 14 as well)
Since IPv6 is not a supported RFE in ODL OSP13 (it will be OSP15 RFE), changing priority to medium.
