Do you have the segment extension enabled?

[Vijendra Soni (vijendra-soni)]

Yes, seems it is enabled.

in /etc/neutron/policy.json

 "create_segment": "rule:admin_only",
 "get_segment": "rule:admin_only",
 "update_segment": "rule:admin_only",
 "delete_segment": "rule:admin_only",

Please find my analysis on above issue:
it's look like there is no neutron api support to create the segment on existing network and also no support
from openstack client side to achive the same.
I am referring https://wiki.openstack.org/wiki/Neutron/ML2#Multi-Segment_Networks specially multisegment comment on this link.
for neutron api referring http://developer.openstack.org/api-ref/networking/v2/index.html but can't see any api to create segment on existing network.

Request for comments on above analysis.
