One was accepted and an editorial change was made in draft-04. The second one was:   -           This document extends the usage of port 3785 adding the function of being the destination port for the S-BFD echo packets. Should not this be regarded as an update of RFC 5881 and mentioned as such on the front page?     The authors answered the following:   -           I do not have a strong opinion one way or another — I will leave this one to the AD’s guidance, and I am happy to mark this document as updating RFC 5881 if that’s the preferred direction   No change was made. I would like to make sure that the responsible AD has seen this comment. It’s not a show-stopper, but I still believe that marking this document as an update to RFC 5881 is better.   Major issues:   Minor issues:   Nits/editorial comments:
