O-bit in LISP is not needed. I told the LUSP-GPE authors this. Because OAM-packets like all other control packets go in UDP port 4342 (where encapsulated packets go in UDP port 4341). And P-bit is not needed and the authors indicated the main motivation was to keep consistent with VXLAN so same hardware design could do both. LISP already has port 8473 for L2 frames. And NSH is a service protocol and should run above the transport layer so should have its own port and can address packets anywhere. Just like any other UDP application. If that packet needs to be encapsulated that is a lower level function. Just like IP packets can go in an MPLS based LSP. > picture? They do mean something about how the packet is handled, don't they? I won't answer that because those bit introductions into the design are indeed design bugs IMO.
