This plugin supports multiple plugin at same time. This plugin is for L3 connectivility
|
|
between networks which are realized by different plugins.This plugin adds new attributes 'flavor:network' and 'flavor:router".
|
|
flavor:network corresponds to specific l2 plugin ( flavor-plugin mapping could be configureable by plugin_list config.
|
|
flavor:router corresponds to specific l3 plugin ( flavor-plugin mapping could be configureable by l3_plugin_list config. Note that Metaplugin can provide l3 functionaliteis for l2 plugin which didn't support l3 extension yet.
|
|
This plugin also support extensions. We can map extension to plugin by using extension_map config.

- flavor
|
|
MetaPlugin supports flavor and provider net extension.
|
|
Metaplugin select plugin_list using flavor.
|
|
One plugin may use multiple flavor value. If the plugin support flavor, it may provide
|
|
multiple flavor of network.
|
|
|
|
- Attribute extension
|
|
Each plugin can use attribute extension such as provider_net, if you specify that in supported_extension_aliases.
|
|
|
|
- providernet
|
|
Vlan ID range of each plugin should be different, since Metaplugin dose not manage that.
|
|
|
|
#- limitations
|
|
|
|
Basically, All plugin should inherit NeutronDbPluginV2.
|
|
Metaplugin assumes all plugin share same Database expecially for IPAM part in NeutronV2 API.
|
|
You can use another plugin if you use ProxyPluginV2, which proxies request to the another neutron server.
|
|
|
|
Example flavor configration for ProxyPluginV2
|
|
|
|
meta_flavor_driver_mappings = "openvswitch:neutron.agent.linux.interface.OVSInterfaceDriver,proxy:neutron.plugins.metaplugin.proxy_neutron_plugin.ProxyPluginV2"
|
|
|
|
- Limited L3 support
|
|
In folsom version, l3 is an extension. There is no way to extend exntension attributes.
|
|
so you can set flavor:router value but you can't get flavor:router value in API output.
|
|
L3 agent dont's support flavor:router.
