VXLAN Data Networks

Virtual eXtensible Local Area Networks () data networks are an alternative to data networks.

A data network is implemented over a range of Network Identifiers (.) This is similar to the option, but allows multiple data networks to be defined over the same physical network using unique defined in segmentation ranges.

Packets sent between over virtual project networks backed by a data network are encapsulated with IP, , and headers and sent as Layer 3 packets. The IP addresses of the source and destination compute nodes are included in the outer IP header.

starlingx

supports two configurations for :

partner

  • Dynamic , see Dynamic VXLAN <dynamic-vxlan>
  • Static , see Static VXLAN <static-vxlan>

Before you can create project networks on a 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.

  • Static VXLAN <static-vxlan>
