Hi, We have updated the OSPF HMAC-SHA authentication draft with the comments that we received on the list and offline.
The updated version has a short section which discusses backwards compatibility, similarities and differences from using MD5 (which is explained in Section 5 of 2328), etc. http://www.ietf.org/internet-drafts/draft-bhatia-manral-white-ospf-hmac-sha- 02.txt Please let us know if there are further modifications desired.
