      Description

      After moving an IPv6 host e.g. h1v6 from port-3 to port-8 on s001 and rediscovering it with

      mininet> h1v6 ndisc6 -r 1 -w 1000 1020::3fe h1v6-eth1

      We see the following NS packet sent by this host

      16:02:04.274074 00:bb:00:00:00:01 > 33:33:ff:00:03:fe, ethertype IPv6 (0x86dd), length 86: fe80::2bb:ff:fe00:1 > ff02::1:ff00:3fe: ICMP6, neighbor solicitation, who has 1020::3fe, length 32

      However ONOS only discovers this host with its link-local IP

      id=00:BB:00:00:00:01/None, mac=00:BB:00:00:00:01, locations=[of:0000000000000001/8], vlan=None, ip(s)=[fe80::2bb:ff:fe00:1], innerVlan=None, outerTPID=unknown, provider=of:org.onosproject.provider.host, configured=false

      See onos-diags for more details.
