Thanks Hitoshi.  And with the recent additional support from several folks 
on the list, we will now begin the process to advance the doc.  Thanks 
all.

| Hello folks,
| 
| We received comments from Jake/Lenny and Mankamana during the WGLC for the mtrace2 draft.
| We then applied the comments to the draft and have submitted the revised one.
| 
| The followings are the summary of the changes.
| If there are no other concerns or comments, we'd like to ask chairs to move it forward.
| 
| Changes:
| 
| 1. section 1, add the following sentence to clarify the target and scope of this document;
| 
| "This document describes the base specification of Mtrace2 that can serve as a basis for future proposals such as Mtrace2 for AMT [9] and Mtrace2 for MVPN [10]. They are therefore out of the scope of this document."
| 
| 2. section 3.2.2, add the following sentence at the end of the first paragraph to make the meaning more clearer;
| 
| "If the actual number of hops is not known, an Mtrace2 client could send an initial Query message with a large # Hops (e.g., 0xffffffff), in order to try to trace the full path."
| 
| 3. section 4.4, change the first paragraph as follows, to clearly explain the meaning;
| 
| "An Mtrace2 Reply MUST be returned to the client by a router if any of the following conditions occur:
| 
| 1.  The total number of the traced routers are equal to the # of hops
|     in the request (including the one just added) plus the number of
|     the returned blocks, if any.
| 
| 2.  Appending the Standard Response Block would make the Mtrace2
|     Request packet longer than the MTU of the Incoming interface.
|     (In case of IPv6 not more than 1280 bytes; see Section 4.3.3 for
|     additional details on handling of this case.)
| 
| 3.  The request has reached the RP for a non source specific query or
|     has reached the first hop router for a source specific query (see
|     Section 4.2.2, items 9 and 10 for additional details)."
|
