The Bidirectional Forwarding Detection (BFD) protocol is commonly
used to verify connectivity between two systems. BFD packets are
typically very small. It is desirable in some circumstances to know
not only that the path between two systems is reachable, but also
that it is capable of carrying a payload of a particular size. This
document specifies how to implement such a mechanism using BFD in
Asynchronous mode.
YANG modules for managing this mechanism are also defined in this
document. These YANG modules augment the existing BFD YANG modules
defined in RFC 9314. The YANG modules in this document conform to the
Network Management Datastore Architecture (NMDA) (RFC 8342).
This document is a product of the Bidirectional Forwarding Detection 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.
