Unaffiliated Bidirectional Forwarding Detection (BFD) Echo
RFC 9747

Received changes through RFC Editor sync (created document RFC 9747, created became rfc relationship between draft-ietf-bfd-unaffiliated-echo and RFC 9747, set abstract to 'This document specifies an extension to the Bidirectional Forwarding Detection (BFD) protocol that enables the use of the BFD Echo function without the need for an associated BFD control session. This "Unaffiliated BFD Echo" mechanism allows rapid detection of forwarding path failures in networks where establishing BFD control sessions is impractical or undesirable. By decoupling the Echo function from the control plane, network devices can utilize BFD's fast failure detection capabilities in a simplified manner, enhancing network resiliency and operational efficiency.

This document updates RFC 5880 by defining a new Unaffiliated BFD Echo mechanism.', set pages to 12, set standardization level to Proposed Standard, added RFC published event at 2025-03-26, created updates relation between RFC 9747 and RFC 5880)
