A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Link State Routing WG of the IETF.

        Title           : OSPF Strict-Mode for BFD
        Authors         : Ketan Talaulikar
                          Peter Psenak

Abstract:
   This document specifies the extensions to OSPF that enable an OSPF
   router to signal the requirement for a Bidirectional Forwarding
   Detection (BFD) session prior to adjacency formation.  Link-Local
   Signaling (LLS) is used to advertise this requirement of "strict-
   mode" of BFD session establishment for OSPF adjacency.  If both OSPF
   neighbors advertise the "strict-mode" of BFD, adjacency formation
   will be blocked until a BFD session has been successfully
   established.
