The configuration supports multiple VXLAN self-service networks. For
|
|
simplicity, the following procedure creates one self-service network and
|
|
a router with a gateway on the flat provider network. The router uses
|
|
NAT for IPv4 network traffic and directly routes IPv6 network traffic.
|
|
|
|
.. note::
|
|
|
|
IPv6 connectivity with self-service networks often requires addition of
|
|
static routes to nodes and physical network infrastructure.
|
|
|
|
#. Source the administrative project credentials.
|
|
#. Update the provider network to support external connectivity for
|
|
self-service networks.

|
|
|
.. code-block:: console
|
|
|

$ openstack network set --external provider1

This command provides no output.
