Summary: Ready with minor issues


The document is well written and complete, but requires a good understanding of BFD (RFC 5880) and of the use-cases (draft-ietf-bfd-seamless-use-case) document. A few minor issues are listed below, it would be good to address them, but
 none is a show-stopper. 


Major issues:


Minor issues:




In the introduction I see the following:




   One key aspect of the mechanism described in this document eliminates

   the time between a network node wanting to perform a continuity test

   and completing the continuity test.  


I am wondering if this is really what is intended. If I understand correctly, S-BFD does not eliminate the continuity test but the set-up states transitions before the continuity test starts. Would not that
 rather be ‘… and starting the continuity test.’?




In the last paragraph of Section 5:




Note that incoming S-BFD control packets may be IPv4, IPv6 or MPLS



If these are the only three options I suggest that the text explicitly specify this. If other options are possible or may be possible in the future I suggest that the text also clarifies this


Nits/editorial comments:




Second paragraph in Section 3: s/allocated toby a remote node/allocated to by a remote node/
