Hi All,

Uptil this version, all Erratas on RFC4379 has been addressed and text
were updated to reflect TC instead of EXP (RFC5462).

As mentioned in Section 1.5 of draft-smack-mpls-rfc4379bis, the next step
is to evaluate the RFCs that updates RFC4379 and identify the list to be
incorporated in rfc4379bis.


A summary of updates by RFC 6424:

* Updates the validation procedure to include Stitching and Hierarchical
LSPs.
* Deprecates DSMAP defined in RFC4379 and replaces it with DDMAP.
* Introduces a new TLV as FEC Stack Change Sub-TLV
* Introduces 2 New return codes.
* Check and include IANA considerations.

Potential Update - Update the return code and DDMAP TLV in respective
section, Remove (or Deprecate DSMAP), update the procedure with DDMAP
reference in place of DSMAP, Update the procedure section 4.4, 4.5 and 4.6.

A summary of updates by RFC 6425:

* Extends the validation procedure for P2MP and MP2MP LSPs.
* Introduces 4 new Target FEC Stack Sub-TLVs.
* Introduces 2 new TLVs (and related Sub-TLVs)
* Check and include IANA considerations.


Potential Update - Per discussion with WG.

A summary of updates by RFC 6426:

* Extends the validation procedure for MPLS-TP with both IP based and
non-IP (ACH) based encapsulation .
* Introduces 2 new Target FEC Stack Sub-TLVs.
* Introduces new Address types for DSMAP
* Introduces 3 new TLVs.
* Reserves a flag in Global Flags.
* Check and include IANA considerations.



Potential Update - Per discussion with WG.

A summary of updates by RFC 6829:

* Introduces 2 new Target FEC Stack Sub-TLVs for PW between IPv6 endpoints.
* No changes in procedure.
* Check and include IANA considerations.



Potential Update - Include the Sub-TLVs in respective section.

A summary of updates by RFC 7506:

* Introduces a new option in IPv6 HbH extension header.
* No changes in procedure.
* Check and include IANA considerations.



Potential Update - Include the same and update the header processing
section.

A summary of updates by RFC 7537:

* Document to create IANA registries for name spaces defined in RFC4379
and 6424.
* No changes in procedure.
* Check and include IANA considerations.



Potential Update - Include the same in IANA consideration.

Since RFC 6829 and 7506 are straight forward, we will go ahead and include
the same while we discuss on the other RFCs. Please share your thoughts
and accordingly, we can include the relevant content to update the draft.

Thanks,
Nagendra
