Networking#

Get answers to common technical questions about networking for Rackspace Private Cloud Powered By OpenStack (RPCO) v13.

Why does RPCO supporting OpenStack Networking (neutron) by default?

The OpenStack community is moving forward with neutron, and RPCO will remain in sync with community development.

Why is RPCO using Linux Bridge plug-in?

The Linux Bridge plug-in is known to be stable with OpenStack Networking and can be used to create bridges within containers.

What advantages do containers offer in configuring OpenStack Networking?

Namespaces, taps, tunnels, VLAN-tagged interfaces, vEth-pairs, iptables, and other kinds of network technology are all fully functional inside containers. Containers also provide scalability and the ability to work around restrictions of one external network per L3 agent.

Do I have do anything differently when networking roles are assigned to separate networking nodes?

In this scenario, you would modify the host rpc_user_config.yml file with the new host(s) information under the network_hosts group.

After the new hosts are active and functional, delete the old containers, remove the old container information from the openstack_inventory.json file, and update the neutron database to reflect the deleted nodes.

The environment is fully configurable. While RPCO has specified groups and populated those groups, it is possible to make changes in the rpc_environment.yml file.
