Comment 4 Jakub Libosvar 2015-12-15 16:25:22 UTC 
In the ks_settings.yml I see CONFIG_NEUTRON_ML2_TUNNEL_ID_RANGES: 1:1000 which sets tunnel_id_ranges to ml2.conf. That means your maximal value is 1000

If closing this bug as NOTABUG. If you still see the issue after setting tunnel_id_ranges to 1:4294967294, feel free to re-open.
