Alvaro, Here is a small review comment on draft-ietf-spring-bfd.
In section 6, discussing BFD Echo (not Echo BFD), the text states: "A BFD Control packet MAY be used as the payload of Echo BFD." BFD Unaffiliated Echo[1] has recently been sent to the IESG. The work in that draft covers the details for BFD to "talk to itself". I'd suggest leveraging this as a reference in the spring document. Note that the binding SID specific text is still appropriate in the spring document. Beyond that, the document is straight forward and captures the expected discussion points for use of BFD in a spring environment. I'd encourage the spring chairs to also reach out to the MPLS working group for detailed review of the LSP Ping updates. They look fine to me, but I lack depth in those procedures. -- Jeff [1] https://datatracker.ietf.org/doc/html/draft-ietf-bfd-unaffiliated-echo-14 > On Dec 2, 2024, at 2:51 PM, Alvaro Retana <aretana.i...@gmail.com> wrote: > > [Sorry for the bad formatting. :-(] > > [cc'ing the bfd WG] > > > Dear WG: > > This message starts a two-week WG Last Call for draft-ietf-spring-bfd, ending > on December/16.
