The IESG has approved the following document: - 'BFD Encapsulated in Large Packets' (draft-ietf-bfd-large-packets-16.txt) as Proposed Standard
This document is the product of the Bidirectional Forwarding Detection Working Group. The IESG contact persons are Gunter Van de Velde, Jim Guichard, Éric Vyncke and John Scudder. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-bfd-large-packets/ Technical Summary 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 that not only is the path between two systems 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). Working Group Summary This document reached broad agreement in the BFD WG. There was no controversy. The only unaddressed feedback was (from Robert Raszuk) that the solution does not work well with ECMP. This is not specific to this document but is a general issue with BFD multi-hop. This document doesn't change the fundamentals of BFD and while Robert's observation is correct, this document follows what is already done in BFD multi-hop. Document Quality YANG doctors made a review and their comment was addressed in -14. Personnel The Document Shepherd for this document is Reshad Rahman. The Responsible Area Director is Éric Vyncke. IANA Note Nothing beside registering the small YANG module.
