"BFD Management Information Base", Thomas Nadeau, Zafar Ali, Nobo Akiya, 26-Apr-09. ( bytes)

This draft defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes managed objects for modeling Bidirectional Forwarding Detection (BFD) protocol.

"BFD For MPLS LSPs", Rahul Aggarwal, Kireeti Kompella, Thomas Nadeau, George Swallow, 20-Jun-08. ( bytes)

One desirable application of Bi-directional Forwarding Detection (BFD) is to detect a Multi Protocol Label Switched (MPLS) Label Switched Path (LSP) data plane failure. LSP-Ping is an existing mechanism for detecting MPLS data plane failures and for verifying the MPLS LSP data plane against the control plane. BFD can be used for the former, but not for the latter. However the control plane processing required for BFD control packets is relatively smaller than the processing required for LSP-Ping messages. A combination of LSP-Ping and BFD can be used to provide faster data plane failure detection and/or make it possible to provide such detection on a greater number of LSPs. This document describes the applicability of BFD in relation to LSP-Ping for this application. It also describes procedures for using BFD in this environment.

"Bidirectional Forwarding Detection", Dave Katz, David Ward, 5-Feb-09. ( bytes)

This document describes a protocol intended to detect faults in the bidirectional path between two forwarding engines, including interfaces, data link(s), and to the extent possible the forwarding engines themselves, with potentially very low latency. It operates independently of media, data protocols, and routing protocols.

"BFD for Multihop Paths", Dave Katz, David Ward, 5-Feb-09. ( bytes)

This document describes the use of the Bidirectional Forwarding Detection protocol (BFD) over multihop paths, including unidirectional links.

"BFD for IPv4 and IPv6 (Single Hop)", Dave Katz, David Ward, 5-Feb-09. ( bytes)

This document describes the use of the Bidirectional Forwarding Detection protocol over IPv4 and IPv6 for single IP hops.

"Generic Application of BFD", Dave Katz, David Ward, 5-Feb-09. ( bytes)

This document describes the generic application of the Bidirectional Forwarding Detection (BFD) protocol.

"BFD for Multipoint Networks", Dave Katz, David Ward, 5-Feb-09. ( bytes)

This document describes extensions to the Bidirectional Forwarding Detection (BFD) protocol for its use in multipoint and multicast networks. Comments on this draft should be directed to rtg- bfd@ietf.org.
