Hi Toke,

The rational has to do with what a data model like YANG does with router-id. To it the router-id is a key, in the form of a string. That string has to be unique. YANG does not prevent it being a string of zeros or ones, provided that string is unique. Thus the dropping of the "MUST NOT” and the addition of “MUST”.

Thanks.
