The Bidirectional Forwarding Detection (BFD) protocol (RFC 5880) is
used to detect loss of connectivity between two forwarding engines,
typically with low latency. BFD is leveraged by routing protocols,
including the Border Gateway Protocol (BGP), to bring down routing
protocol connections more quickly than the original protocol timers.
This document defines a subcode for the BGP Cease NOTIFICATION
message (Section 6.7 of RFC 4271) for use when a BGP connection is
being closed due to a BFD session going down.
This document is a product of the Inter-Domain Routing Working Group of the
IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
