4. Model / Doc Split
Joint document (draft-ietf-mpls-ldp-mldp-yang) covering both LDP and mLDP:
Total 114 pages – Too big !!!
One of the MPLS-RT comment was to consider model / document split between LDP and mLDP.
Team worked on the split and just posted the two documents (replacing joint draft-ietf-mpls-ldp-mldp-yang)
LDP: draft-ietf-mpls-ldp-yang
mLDP: draft-ietf-mpls-mldp-yang
The split documents also have some cleanup and address couple more MPLS-RT comments:
label-policy config etc.

5. MPLS RT: Pending Comments
Lot of features and objects
The team reviewed and have cut down on some features and/or made them vendor private
Partition into “base” and “extended” parts
Team almost done with categorization of LDP and mLDP features/items in “base” vs “extended”
Next revisions to be posted shortly with both the above comments addressed

6. Pending/Open items Revisit and cut-down on the scope of the document
Split the model into a base and extended items
(Re-)align with regards to OPSTATE decision
Specify default values for RFC-defined configuration parameters
Add statistics for mLDP root LSPs and bindings

7. Next Steps Post new revisions for LDP and mLDP:
Partition into “base” and “extended” model
Realign with respect to OP-STATE
Address some of OPEN items
