This documentation was recently reorganized for clarity. The new
version says the following.
These options apply to logical ports with type of localnet.
options : network_name: optional string
Required. ovn-controller uses the configuration entry
ovn-bridge-mappings to determine how to connect to this network.
ovn-bridge-mappings is a list of network names mapped to a local
OVS bridge that provides access to that network. An example of
configuring ovn-bridge-mappings would be:
$ ovs-vsctl set open . external-ids:ovn-bridge-mappings=physnet1:br-eth0,physnet2:br-eth1
When a logical switch has a localnet port attached, every chas‐
sis that may have a local vif attached to that logical switch
must have a bridge mapping configured to reach that localnet.
Traffic that arrives on a localnet port is never forwarded over
a tunnel to another chassis.
tag: optional integer, in range 1 to 4,095
If set, indicates that the port represents a connection to a
specific VLAN on a locally accessible network. The VLAN ID is
used to match incoming traffic and is also added to outgoing
