Off-list discussion with Tony Przygienda did suggest the following can use some clarification: On Tue, Mar 16, 2021 at 05:02:03PM -0400, Jeffrey Haas wrote: > > GTSM: MANDATORY > If you're using GTSM for your sessions, TCP may not even establish unless > it's on. > > Robert points out existing security considerations about using GTSM. > They apply here as well. > > --- > > BFD Configuration: OPTIONAL? > > Some BGP implementations don't let their sessions come up or stay up if > there's a mis-match in BFD between the systems. > > See draft-ietf-idr-bgp-bfd-strict-mode.

BFD needs to know if it's running or not. BFD itself handles negotiating sessions. No parameters need to be exchanged. BFD session type is derived from the IP address of the session. -- Jeff
