Hello Adam

Many thanks for your review 😊 

Please see below:

 
> 1. In the first exchange with a 6LR: "When a 6LR receives a NS(EARO)
> registration with a new Crypto-ID as a ROVR, it SHOULD challenge by
> responding with a NA(EARO) with a status of "Validation Requested"". Under
> what circumstances would a challenge not be warranted? In other words, could
> this SHOULD be a MUST?

Yes I guess it is a MUST, unless the registration is rejected for another reason, e.g., the overflow below.
Unless someone posts against it I'll make the change with the next revision.


> 2. The following sentence in 7.1 reads, "The 6LR must protect itself against
> overflows and reject excessive registration with a status 2 "Neighbor Cache
> Full"". Does that need to be a MUST instead of a must?

Yes, I suppose so. I'll make that change too.

Many thanks again Adam!

Pascal
