ofagent: physical interface mappings
|
|
====================================

https://blueprints.launchpad.net/neutron/+spec/ofagent-physical-interface-mappings
|
|
|
|
Problem description
|
|
===================
|
|
|
|
ofagent currently has "bridge_mappings" config option inherited
|
|
from ovs agent. it assumes multiple bridges are available.
|
|
the assumption is ok for ovs agent but not desirable for ofagent.
|
|
|
|
Proposed change
|
|
===============
|
|
|
|
* introduce "physical_interface_mappings" config option for ofagent
|
|
with a similar semantics to linuxbridge.
|
|
|
|
* deprecate bridge_mappings for ofagent later.
|
|
|
|
* document the upgrade procedure for deployers.

Other deployer impact
|
|
---------------------
|
|
|
|
a deployer who's using ofagent might need to tweak his configuration.
|
|
|
|
* create veth pairs for each bridges in the existing bridge_mappings
|
|
|
|
* use physical_interface_mappings instead of bridge_mappings
