Hi Bryant,

Thank you for taking the time to go through the document.

OK, we'll copy some text from the introduction section to the abstract
section to provide a better pitch why one would want to read this
document.

It is my understanding that RFC 8092 "BGP Large Communities" are just
like RFC 1997 "BGP Communities", but ...  larger (for lack of better
words). Referencing RFC 7454 seems plenteous.

So, what if there are not any additional considerations, If there were,
they would've been (or are) covered in RFC 8092's security section,
right?

This is an Internet-Draft targetted for Informational status, I'm not
sure what you expect here.

What reference would you suggest? You feel the section 2.2 text cannot
stand on its own?

Kind regards,
