Hello BFD experts,

after some feedback Nobo and me updated the document. We changed the wording from "Mandatory interval support" towards "Standardized interval support". The "Mandatory" was an unfortunate word choice and caused confusion; my apology for this.

We also added some clarifications.

To summarize this draft is about an interoperability problem between BFD speakers when the number of supported intervals is small, as it may happen with hardware-based BFD. Such implementations are more difficult to upgrade (or even impossible), compared to software on general-purpose CPU, thus the attempt to avoid a foreseeable problem.

Discussions are welcome :-)

Best Regards,
Nobo & Marc
