Made paths to include files relative to doc source. This is needed for downstream builds and is good practice for reusability. Fixed some include statements with broken syntax. Added missing section labels to include file.

VXLAN Data Networks
|
|
===================
|
|
|
|
Virtual eXtensible Local Area Networks \(|VXLANs|\) data networks are an
|
|
alternative to |VLAN| data networks.
|
|
|
|
A |VXLAN| data network is implemented over a range of |VXLAN| Network
|
|
Identifiers \(|VNIs|.\) This is similar to the |VLAN| option, but allows
|
|
multiple data networks to be defined over the same physical network using
|
|
unique |VNIs| defined in segmentation ranges.
|
|
|
|
Packets sent between |VMs| over virtual project networks backed by a |VXLAN|
|
|
data network are encapsulated with IP, |UDP|, and |VXLAN| headers and sent as
|
|
Layer 3 packets. The IP addresses of the source and destination compute nodes
|
|
are included in the outer IP header.
|

|
|
|
|
|prod-os| supports two configurations for |VXLANs|:

|
Before you can create project networks on a |VXLAN| provider network, you must
|
|
define at least one network segment range.
|
|
|
|
.. note::
|
|
|
|
Static VXLAN is limited to one data network, and if configured, it must
|
|
be enabled on all openstack-compute labeled nodes.
