Enhances provider extension to support flat networks and VLANs on multiple physical networks. Implements blueprint provider-networks. To create a flat network using the CLI with admin rights: net-create --tenant_id <tenant-id> <net-name> --provider:network_type flat --provider:physical_network <physical-network> To create a VLAN network using the CLI with admin rights: net-create --tenant_id <tenant-id> <net-name> --provider:network_type vlan --provider:physical_network <physical-network> --provider:vlan_id <vlan-id> The provider extension is supported by the linuxbridge and openvswitch plugins and their agents [openvswitch phase 2 implementation is in-progress, and does not yet support flat networks or multiple interfaces]. Ranges of VLANs available on named physical networks for normal allocation are specified in the plugin's config file via the ListOpt syntax: network_vlan_ranges = <physical_network>:<vlan_min>:<vlan_max> The mapping of each named physical network to its physical network interface is specified (per-agent-host) in the agent's config file via the ListOpt syntax: physical_interface_mappings = <physical_network>:<physical_interface> See quantum/plugins/linuxbridge/README for details and examples of network_vlan_ranges and physical_interface_mappings usage. Also, bulk operations are enabled for the linuxbridge plugin. Change-Id: I93402bd5cc6316e9408ea71c3b3989d06898ee30

|

This class is used by quantum's extension framework to make
|
|
metadata about the provider network extension available to
|
|
clients. No new resources are defined by this extension. Instead,
|
|
the existing network resource's request and response messages are
|
|
extended with attributes in the provider namespace.
|
|
|
|
To create a provider VLAN network using the CLI with admin rights:
|
|
|
|
(shell) net-create --tenant_id <tenant-id> <net-name> \
|
|
--provider:vlan_id <vlan-id>
|
|
|
|
With admin rights, network dictionaries returned from CLI commands
|
|
will also include provider attributes.
