-This guide assumes a point-to-point tunnel between two VMs connected to OVS
-bridges on different hypervisors connected via IPv4. Of course, more than one
-VM may be connected to any of the hypervisors, using the same LISP tunnel, and
-a hypervisor may be connected to several hypervisors over different LISP
-tunnels.
+This guide assumes tunneling between two VMs connected to OVS bridges on
+different hypervisors reachable over IPv4. Of course, more than one VM may be
+connected to any of the hypervisors, and a hypervisor may communicate with
+several different hypervisors over the same lisp tunneling interface. A LISP
+"map-cache" can be implemented using flows, see example at the bottom of this
+file.
