Hi Qin,

On Sun, Apr 12, 2020 at 8:12 PM Qin Wu <bill.wu@huawei.com<mailto:bill.wu@huawei.com>> wrote:
Section 2:
* "All security sensitive data (i.e., private keys, passwords, etc.)  SHOULD be overwritten ..." presents a choice.  Why would an implementer not do this? *
[Qin]: This was outcome of the discussion, see the following link:
https://mailarchive.ietf.org/arch/msg/netmod/qrU_71AkP42lnkR6KnfaMsoSgCs/
i.e., folks concerned to restore security data and password to default value, that's we introduce clean requirements to address this concern.
"Implementors SHOULD reboot the device or otherwise restart processes needed to bootstrap it." leads me to the same question.
[Qin]: To make default configuration take effect, the device reboot is recommended, but in some case, the IP address reachability of the device may be lost, therefore bootstrapping may be needed.

For both of these I suggest mentioning in the document the reason it's a SHOULD and not a MUST, i.e., describe a situation when it might be okay to do something other than what it says.

(Reminder: These are not blocking comments, just suggestions.)

Thanks for considering these suggestions.
