Changed paths to avoid '..', which breaks symlinks in newer versions of sphinx. Consolidated installation include files under /_includes. Prefixed r5 versions with 'r5_' Moved files that are used up/down, but at different paths under /shared/_includes and /shared/figures Move two include files to /_includes Moved addtional images to /shared/figures/... Required for DS platform builds. Signed-off-by: Ron Stone <ronald.stone@windriver.com> Change-Id: Ia38f4205c5803b3d1fc043e6c59617c34a4e5cbd Signed-off-by: Ron Stone <ronald.stone@windriver.com>

Static VXLAN
|
|
============
|
|
|
|
The static unicast mode relies on the mapping of neutron ports to compute nodes
|
|
to receive the packet in order to reach the |VM|.
|
|
|
|
.. only:: starlingx
|
|
|
|
In this mode there is no multicast addressing and no multicast packets are
|
|
sent from the compute nodes, neither is there any learning. In contrast to
|
|
the dynamic |VXLAN| mode, any packets destined to unknown MAC addresses are
|
|
dropped. To ensure that there are no unknown endpoints the system examines
|
|
the neutron port DB and gathers the list of mappings between port |MAC|/IP
|
|
addresses and the hostname on which they reside.

Static |VXLAN| is limited to use on one data network. If configured, it must be
|
|
enabled on all OpenStack compute nodes.

`Static Endpoint Distribution`
|
|
|
|
.. note::
|
|
In the static mode there is no dynamic endpoint learning. This means that
|
|
if a node does not have an entry for some destination |MAC| address it will
|
|
not create an entry even if it receives a packet from that device.

Workflow to Configure Static VXLAN Data Networks
|
|
------------------------------------------------
|
|
|
|
Use the following workflow to create static VXLAN data networks and add
|
|
segmentation ranges using the |CLI|.

#. Create a |VXLAN| data network, see :ref:`Adding Data Networks Using the CLI

|
|
#. Add segmentation ranges to static |VXLAN| data networks, see :ref:`Adding
