[NANOG] Re: The Network CLI -- Love it ? Hate it? Needed?

It seems people are confusing “source of truth” with “intended truth”, or maybe people have a different definition of 
truth than I do.

The network is always the only source of truth as it is what is actually deployed in the network, it is the truth about 
what is, while I can intend for that truth to be different, that doesn’t change the reality of the situation.
