Re: FW: New Version Notification for draft-ietf-bfd-rfc5884-bis-00.txt

The following URL is a diff vs. RFC 5884.  Unlike the other diffs, since 
RFC 5884-bis also merges in RFC 7726, please refer separately to that 
document.  The merged text is quite clear in this diff.

https://author-tools.ietf.org/diff?url_1=https://www.rfc-editor.org/rfc/rfc5884.txt&url_2=https://www.ietf.org/archive/id/draft-ietf-bfd-rfc5884-bis-00.txt&iddiff=1\

I have also incorporated 3 known errata for RFC5884 that have already been published. This document is the union of two RFCs (RFC5884 contributing most of the text). It requires a good review from the WG for the flow of the document since two documents got merged. There is a questionnaire to be filled by implementors in the Appendix. If you have experience with implementations/ deployments, please respond to the questionnaire (I will be happy to record your responses in the document if you respond to me over email copying the WG as well).
