A localnet logical switch port bridges a logical switch to a - physical VLAN. A logical switch with a localnet LSP should - have only one other LSP. Some kinds of gateways (see Gateways - below) use a logical switch with a router port as the second LSP. On the - other hand, when the second LSP is a VIF, the logical switch is not really - a logical network, since it is bridged to the physical network rather than - insulated from it, and therefore cannot have independent but overlapping IP - address namespaces, etc. (A deployment might nevertheless choose such a - configuration to take advantage of the OVN control plane and features such - as port security and ACLs.) + physical VLAN.

A localport logical switch port is a special kind of VIF logical switch port. These ports are present in every chassis, not bound
