Mahesh, While reviewing version -10, I had the following questions: For the state machine changes, in the Init->Init state, we have NULL auth. While this is a "boring" transition, it's also happening at a very slow part of the state machine; timers should be once a second. Is there a strong argument to use NULL here? In section 3: : Sequence Number: The sequence number for this packet. Implementation : may use sequence numbers (bfd.XmitAuthSeq) as defined in BFD : [RFC5880], or secure sequence numbers as defined in Secure BFD : Sequence Numbers [I-D.ietf-bfd-secure-sequence-numbers]. In the core BFD spec, it distinguishes between occasional and meticulous modes and uses different code points to determine what you do. I suspect your intent is that we always use meticulous mode here? -- Jeff On Mon, Jul 13, 2020 at 01:56:14PM -0700, Mahesh Jethanandani wrote: > > A New Internet-Draft is available from the on-line Internet-Drafts directories. > > This draft is a work item of the Bidirectional Forwarding Detection WG of the IETF. > > > > Title : Optimizing BFD Authentication > > Authors : Mahesh Jethanandani > > Ashesh Mishra > > Ankur Saxena > > Manav Bhatia > > Filename : draft-ietf-bfd-optimizing-authentication-10.txt > > Pages : 8 > > Date : 2020-07-13 > > > > Abstract: > > This document describes an optimization to BFD Authentication as > > described in Section 6.7 of BFD RFC 5880.
