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