Hi Jeff, I haven't heard that IETF encourages the discussion of the relevance of the IPR Disclosure to the draft it referred to, less the validity of IPR. I always was told to stay away from these topics. As for your question of what is the change proposed in the draft I'll point to section 6.6 RFC 5880 that describes the Demand mode. It states that the periodic transmission of control messages MUST be stopped. The draft defines, and that is what I consider the update to section 6.6, the procedure by which the system in Demand mode initiates the Poll sequence to inform the remote BFD system of RDI. And coming back to WGAP, I don't recall any concerns or questions being brought up on the WG list. The volume of responses was not enthusiastic, I agree, but all were in favor of adopting the draft.
