Santhosh,

 

>From the traceback below it looks like the neutron process is unable to access keystone.

 

2017-01-22 12:21:51.569 14448 ERROR neutron.api.v2.resource DriverError: Driver error: Unable to establish connection to http://127.0.0.1:5000/v2.0/tokens: HTTPConnectionPool(host='127.0.0.1', port=5000): Max retries exceeded with url: /v2.0/tokens (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x7f9f36b91790>: Failed to establish a new connection: [Errno 111] ECONNREFUSED',))

 

So, I would check the neutron.conf settings for keystone like the user/password and that the neutron process can reach keystone on http://127.0.0.1:5000  Maybe there is a bad security group or keystone isn’t running?
