Hi Tom,

Thanks for the review, some replies inline,

On Dec 29, 2017, at 2:53 AM, t.petch <ietfc@btconnect.com<mailto:ietfc@btconnect.com>> wrote:

A couple of IANA thoughts on this I-D;

"This document requests that IANA allocate from the IS-IS TLV
  Codepoints Registry a new TLV, "

- Is there a particular range that this value should come from?

NS> will add the range.


- A note in s.2 asking that TBD be replaced by the value that IANA
allocates might be useful for the RFC Editor.

NS> will do.


- Are the flag bits of this new TLV going to form a new registry?

NS> it is not.


- And a non-IANA thought - what does a receiver do if it receives more
than one such TLV?

NS> In section 2, it mentions "A sender MUST only transmit a single
     Reverse Metric TLV in a IS-IS Hello PDU.”


"This document also request that IANA allocate from the link-attribute
  bit value for sub-TLV 19 of TLV 22."
I struggled to parse this initially.

Perhaps
"This document also requests that IANA allocate a bit from the
'link-attribute bit values for sub-TLV 19 of TLV 22' registry.


NS> OK.

(That registry title is a bit of a mouthful compounded by the lack of
Capitals in the title:-(

The coupling between the request to IANA to allocate the bit and the
actual definition in the body of the I-D is ... well, non-existent.  You
should have a something about the octet with a TBD2 (not a second TBD)
in section 3.6, a TBD2 in the IANA actions and a request that this be
replaced by RFC Editor by the value that IANA allocates.


NS> will do.

thanks.
- Naiming

Yes, a reader can deduce all this but the lack of precision is how
mistakes are made IMO.  RFC5209 has the sort of detail that I would
expect.
