OSPF Bidirectional Forwarding Detection (BFD) Strict-Mode
RFC 9355

Received changes through RFC Editor sync (created alias RFC 9355, changed title to 'OSPF Bidirectional Forwarding Detection (BFD) Strict-Mode', changed abstract to '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 the requirement for strict-mode
BFD session establishment for an OSPF adjacency. If both OSPF
neighbors advertise BFD strict-mode, adjacency formation will be
blocked until a BFD session has been successfully established.

This document updates RFC 2328 by augmenting the OSPF neighbor state
machine with a check for BFD session up before progression from Init
to 2-Way state when operating in OSPF BFD strict-mode.', changed pages to 10, changed standardization level to Proposed Standard, changed state to RFC, added RFC published event at 2023-02-22, changed IESG state to RFC Published, created updates relation between draft-ietf-lsr-ospf-bfd-strict-mode and RFC 2328)
