Hi Steve, Sankarshan,

I'm following the guide "4" for Havana. For what concern Neutron, everything works smooth until the section 13.6 "Configuring an external provider network". I execute these steps as described there:

neutron net-create EXTERNAL_NAME --router:external True --provider:network_type TYPE --provider:physical_network PHYSICAL_NAME --provider:segmentation_id VLAN_TAG
(OK)

neutron subnet-create --gateway GATEWAY --allocation-pool start=IP_RANGE_START,end=IP_RANGE_END --disable-dhcp EXTERNAL_NAME EXTERNAL_CIDR
(OK)

neutron router-create NAME
(OK)

neutron router-gateway-set ROUTER NETWORK
(OK)

(of course I replaced the labels with the proper names, IPs, ID, etc...)

The last command of section 13.6 fails:

neutron router-interface-add myRouter dc8ea9c9-c737-4ab3-8abb-f62284b078f8
400-{u'NeutronError': {u'message': u'Bad router request: Router already has a port on subnet dc8ea9c9-c737-4ab3-8abb-f62284b078f8', u'type': u'BadRequest', u'detail': u''}}


This is my net and subnet list:

bash-4.1$ neutron net-list
+--------------------------------------+---------+-------------------------------------------------------+
| id                                   | name    | subnets                                               |
+--------------------------------------+---------+-------------------------------------------------------+

+--------------------------------------+---------+-------------------------------------------------------+
bash-4.1$ neutron subnet-list
+--------------------------------------+----------------+------------------+--------------------------------------------------------+
| id                                   | name           | cidr             | allocation_pools                                       |
+--------------------------------------+----------------+------------------+--------------------------------------------------------+
| dc8ea9c9-c737-4ab3-8abb-f62284b078f8 | subnet_externa | 192.168.120.0/24 | {"start": "192.168.120.100", "end": "192.168.120.150"} |
+--------------------------------------+----------------+------------------+--------------------------------------------------------+

I've never execute an interface-add for myRouter before, but it says that "Router already has a port".

What am I doing wrong ?

thanks,

	A.
