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:



1.       In the introduction I see the following:



Ø     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.'?



2.       In the last paragraph of Section 5:



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



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:


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