When we create Neutron routers in DVR mode, the routers are created on our Compute nodes instead of the
network node. This allows for a much more distributed layout of routing, and prevents bottlenecks through our
network nodes. In normal operation, the process of creating and deleting routers behaves in the same way as for the Legacy mode, but understanding and troubleshooting them is a little different.
Ensure that you have a suitable client available for using Neutron. If you are using the accompanying Vagrant environment, you can use the
controller node. This has the
python-neutronclient package that provides the neutron command-line client.
If you created this node with Vagrant, you can execute the following command:
vagrant ssh controller
export OS_TENANT_NAME=cookbook export...
