      ipv4 bgp neighbor is up for weeks no problem

       

      ipv6 bgp neighbor comes up for 14 or 15 minutes sometimes 20 minutes....

       

      then it goes down and comes back up

       

      extended ping to ipv6 neighbor is good for all that time, then dies for those 15 or 20 seconds and  then comes back to life....
