Description Numan Siddique 2017-10-03 15:12:27 UTC 
Description of problem:

OVN presently 
  - doesn't support Responding to the Router solicitation requests from the VM's
  - doesn't generate a NS request to resolve the MAC for packets going out of gateway port if the next hop MAC is unknown.

This needs to be supported.

@Numans, is it merged? :)
Comment 5 Numan Siddique 2017-12-11 11:36:07 UTC 
@Miguel - Yes.  In master. So it would be available in OVS 2.9
Comment 10 Toni Freger 2018-05-27 06:38:11 UTC 
Moving back to ASSIGNED.
This RFE depends on https://bugzilla.redhat.com/show_bug.cgi?id=1567735 that targeted to Zstrem release.

Fixed verified on openvswitch-2.9.0-83.el7fdp.1.x86_64
 OpenStack/13.0-RHEL-7/2019-01-22.1/

Created Ipv6 external subnet, remove from OVN mac table all the entries and from VM I pinged to IPv6 external port. I saw that ovn learned the mac address

Thanks to Numan with helping verify this issue.
