Hi

I have setup three nodes to run for Neutron networking, controller node, network node, and compute node. After following chapter 9 in OPENSTACK INSTALLATION GUIDE FOR RED HAT ENTERPRISE LINUX, CENTOS, AND FEDORA - HAVANA to setup all three nodes, I started on configuring the system based on " Create the base Neutron networks".

When I run below command, I got the error as below.

[root@network01 ~]# neutron net-create ext-net -- --router:external=True --provider:network_type gre --provider:segmentation_id 2 400-{u'NeutronError': {u'message': u'Invalid input for operation: gre networks are not enabled.', u'type': u'InvalidInput', u'detail': u''}}

any idea
