==== OVN-Kubernetes secondary network support for sharing a physical network between localnets

When configuring a secondary network that uses the `localnet` topology, you can now specify a physical network name with the `physicalNetworkName` field. By default, this value is set to the name of the localnet. Multiple localnets can share the same physical network.

For more information, see xref:../networking/multiple_networks/secondary_networks/creating-secondary-nwt-ovnk.a
