Hi Danny, I can’t really say. It may be that the help doesn’t differentiate between a user with admin rights or a regular user. Also, if you *don’t* specify those attributes as an admin user, then the network that’s created is bound to the same “limitations" as a non-admin user (ie. What ever is defined in tenant_network_type).

Hi Danny, When 'admin' creates a network they are able to specify the following attributes: - provider:network_type (ie. vxlan, gre, vlan, flat, local) - provider:segmentation_id (ie. 802.1q tag, gre key, vxlan vni) - provider:physical_network (ie. provider label of the physical interface - physnet1, ph-eth1, etc) The following attribute that allows the network to be used as an external network of a router: - router:external (ie. true/false) The following attribute that allows the network to be shared amongst tenants: - shared (ie. true/false) A tenant does not have the ability to specify any of those attributes. If they try, they will be rejected. Tenants should have no visibility into the 'type' of networks they create, and are in fact limited to particular network types and IDs that are specified in the plugin configuration file or ml2_conf.ini. I believe the configuration options are 'tenant_network_type' and 'network_vlan_ranges'. That is why you do not see the provider attributes as the tenant, even though they technically exist for ALL networks, regardless of who created them. Admin users are not restricted by the options in the config file, and can create a network using any network type or segmentation ID that they choose. In Horizon, you will likely only see networks owned by the tenant when you go to the 'Project' tab. In the 'Admin' tab, you would see all networks. Hope that helps, James ________________________________ From: Danny Choi (dannchoi) [[email protected]<mailto:[email protected]>] Sent: Thursday, October 02, 2014 8:14 PM To: [email protected]<mailto:[email protected]> Cc: bxb-openstack-dev(mailer list) Subject: [Openstack] What is the difference between provider network and tenant network?
