# Éric Vyncke, INT AD, comments for draft-ietf-bfd-stability-19
CC @evyncke

Thank you for the work put into this document. I find the idea simple but
useful.

Please find below some non-blocking COMMENT points/nits (replies would be
appreciated even if only for my own education).

Special thanks to Reshad Rahman for the shepherd's detailed write-up including
the WG consensus and the *some* justification of the intended status. I am
puzzled though by `No implementations and no known plans to implement.` ...

I hope that this review helps to improve the document,

Regards,

-éric

## COMMENTS (non-blocking)

### No implementation plans ?

[This is the same comment as for draft-ietf-bfd-secure-sequence-numbers-23, but
as there is no crypto at all and the mechanism is different, I fail to see why
there are no implementations planned]

Per shepherd's write-up: `No implementations and no known plans to implement.`
... This is rather sad for a set of 3 I-Ds.

### Stability or reliability ?

No need to reply but I would have expected this work be around "reliability"
(i.e., packet loss rate) rather than "stability" (i.e., whether the link flips
up/down).

### Section 1

s/it receives at least one packet/it receives at least one *BFD* packet/ ?

### Section 4

I am puzzled as it appears that this mechanism can only be configured via a
YANG data model ? I.e., no PCEP, no GUI, no CLI ? Text should probably be more
open than only YANG. E.g., s/*is* achieved by configuring /*may be* achieved by
configuring /

### Section 5

Which header in `If the Authentication Present (A) bit is set in the header` ?

### Section 6

s/When using MD5 or SHA authentication/When using MD5 or *SHA1* authentication/
?

### Section 5

The end of the section is about the operations to be done by the receiver.
Isn't this redundant with section 6 ? Suggest to remove the last 3 paragraphs
of this section to avoid redundancy.

### Section 8

It is usually useful to provide the exact URI to existing registries when
requesting changes in these registries.

### Appendix B.1

Thanks for the IPv6 example :-)

Note: you may want to use more recent dates than 2016 ;-)
