Hi Tony,

Thanks the update.
1 clarification question on §5 (new capability)

« If all routers in an area advertise the Multi-part TLV Capability a node MAY 
advertise multi-part TLVs "



Does this mean that if one router does not advertise the capability, routers 
MUST NOT advertise multi-part TLVs? (and if necessary readvertises LSPs which 
contained such multi-part TLV)

If so, I would favor adding this explicitly.

Regards,
--Bruno

Hi all,

This is an update to reflect some of the discussions to date. A diff is 
attached.  Most of this is a change to terminology to stop using the word 
'instance' and shift to using 'multi-part TLV'.

We have been having a discussion about adding more discussion of keys in this 
document.  We have not done that yet.  This is not an indication of refusal, 
just making one baby step forward.  More to come... Text contributions are more 
than welcome.

Other comments?

Regards,
Tony

Abstract:
  New technologies are adding new information into IS-IS while
  deployment scales are simultaneously increasing, causing the contents
  of many critical TLVs to exceed the currently supported limit of 255
  octets.  Extensions such as [RFC7356] require significant IS-IS
  changes that could help address the problem, but a less drastic
  solution would be beneficial.  This document codifies the common
  mechanism of extending the TLV content space through multiple TLVs.
