This document specifies extensions to RFC4271 BGP-4 that enable a BGP speaker to signal additional Bidirectional Forwarding Detection (BFD) extensions using an optional parameter BFD capability. This BFD capability enables a BGP speaker to prevent a BGP session from being established until a BFD session is established. It is referred to as BGP BFD "strict-mode". BGP BFD strict-mode will be supported when both the local speaker and its remote peer are BFD strict-mode capable, Otherwise, a BGP speaker and its peer should not require a BFD session for BGP session establishment.
