Hi, Les:

 

I have reviewed again this revised draft, and contrary to your declaration that 
"it addressed all the comments/issues", IT IS NOT. 

Here are my analysis:

 

1) The document states in several places that the key is necessary for the 
right process of MP-TLV, and gives two examples for the TLV 22 and TLV 135, 
their respective key definitions, but, there is no key definition for other 
code points.

 

2) If you think it is impossible to define the key definition for all the 
MP-TLV applicable TLV that you list in the sec 8.1(IANA consideration) in your 
document, then this is the WRONG direction to solve the MP-TLV related problem.

  If you can't define such key information, the interoperability problem will 
be arose within the operator network.

 

3) Such consideration is same for the MP-TLV Capability Advertisement. In your 
solution, MP-TLV capability advertisement is not per-codepoint basis, then how 
you require the operator " diligence is still required on the part of the 
operator to ensure that configurations which require the sending of MP-TLV for 
a given codepoint are not introduced on any node in the network until all nodes 
in the network support MP-TLV for the relevant codepoints." ? By manual? By 
other OOB methods?

 

4) Based on the above comments, I think your draft should be renamed as "MP-TLV 
Key Definition for IS-IS TLV 22 and TLV 135", it is far to be evaluated as one 
general solution for MP-TLV problem.

 

I can't see other values except the key definition of TLV 22 and TLV 135 from 
the current version.

Following such direction, the operator will be busy to coordinate the vendors, 
the deployment for the opened Pandora's box

   Title:   Multi-part TLVs in IS-IS

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 exist that 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.
