Neutron VPNaaS (VPN-as-a-Service)
|
||||
================================
|
||||
|
||||
Preparation and deployment
|
||||
--------------------------
|
||||
|
||||
Modify the configuration file ``/etc/kolla/globals.yml`` and change
|
||||
the following:
|
||||
|
||||
::
|
||||
|
||||
enable_neutron_vpnaas: "yes"
|
||||
|
||||
Verification
|
||||
------------
|
||||
|
||||
VPNaaS is a complex subject, hence this document provides directions for a
|
||||
simple smoke test to verify the service is up and running.
|
||||
|
||||
On the network node(s), the ``neutron_vpnaas_agent`` should be up (image naming
|
||||
and versioning may differ depending on deploy configuration):
|
||||
|
||||
::
|
||||
|
||||
docker ps --filter name=neutron_vpnaas_agent
|
||||
CONTAINER ID IMAGE
|
||||
COMMAND CREATED STATUS PORTS
|
||||
NAMES
|
||||
97d25657d55e
|
||||
operator:5000/kolla/oraclelinux-source-neutron-vpnaas-agent:4.0.0
|
||||
"kolla_start" 44 minutes ago Up 44 minutes
|
||||
neutron_vpnaas_agent
|
||||
|
||||
kolla-ansible includes a small script that can be used in tandem with
|
||||
``tools/init-runonce`` to verify the VPN using two routers and two Nova VMs:
|
||||
|
||||
::
|
||||
|
||||
tools/init-runonce
|
||||
tools/init-vpn
|
||||
|
||||
Verify both VPN services are active:
|
||||
|
||||
::
|
||||
|
||||
neutron vpn-service-list

||||

|
||||
+--------------------------------------+----------+--------------------------------------+--------+
|
||||
|
||||
Two VMs can now be booted, one on vpn_east, the other on vpn_west, and
|
||||
encrypted ping packets observed being sent from one to the other.
