Reviewing DVR Code

All of the DVR code can be found on the bp/neutron-ovs-dvr gerrit topic. However, if you want to review the patches that matter the most now, you'll want to read this guide. The bulk of the functionality is handled by these patches:

The work is still in progress, however a devstack patch is available to ease the merging pain and test all the patches at ones, also providing some API coverage. This is still a WIP; more to follow.

Enabling Distributed Virtual Routing Functionality in OpenStack Neutron

This wiki provides information on HowTo Configure and deploy the Distributed Virtual Router functionality in the current OpenStack Neutron implementations.


The configuration section will provide information on all the config parameters that need to be set before deploying the Distributed Virtual Router. There are Global Configurations that need to be set and as well as the Agent specific configurations that need to be set.

Note: Be sure that your firewall or security groups allows UDP traffic over the vxlan port to pass between the hosts

  • In its initial form, DVR will depend on ml2/ovs and vxlan.
  • l2pop
L3 Agent.ini
L2 Agent.ini (ml2_conf.ini)
  • ml2 section: append ",l2population" to mechanism_drivers
  • agent section: l2_population = True
