+ <p>
+ There are two kinds of logical switches, that is, ones that fully
+ virtualize the network (overlay logical switches) and ones that provide
+ simple connectivity to a physical network (bridged logical switches).
+ They work in the same way when providing connectivity between logical
+ ports on same chasis, but differently when connecting remote logical
+ ports. Overlay logical switches connect remote logical ports by tunnels,
+ while bridged logical switches provide connectivity to remote ports by
+ bridging the packets to directly connected physical L2 segment with the
+ help of <code>localnet</code> ports. Each bridged logical switch has
+ one and only one <code>localnet</code> port, which has only one special
+ address <code>unknown</code>.
