      Description of problem:

      After IPI installing a 3-node Hub Cluster, and converting them to dual stack, fd69::/125 address is seen in the Baremetal br-ex interface

      Version-Release number of selected component (if applicable):

      4.12.0

      How reproducible:

      Ranodmly reproduced and this IP is assigned in one of the 3 master hub cluster nodes

      Steps to Reproduce:

      1. IPI install 4.12.0
2. Use the Convert from IPv4/IPv6 dual stack procedure. 
3.

      Actual results:

      Check for the IP fd69::/125 in the br-ex interface

      OVN CrashLoopBackOff

      Expected results:

      The IP is a internal OVNKUBE IP, and it should not appear on the interface.
      fd69::2/125 should be present on br-ex, but make sure fd69::2 does not :

      1. show up as an address in the node Status.Addresses list at all
      2. exist in any Node object annotations

      Additional info:

      This is one of the issues in IPv6 that is discovered, the other issue is linked here as well.
