>  Thanks for your comments, I can start a email thread outlining the background of the draft. The base idea of the draft is an extension of the RLOC receiver TLV specified in RFC8059. While RFC8059 defined the TLV for Ingress Replication (LISP Multicast over Unicast tunnels), the new draft tries to define TLVs needed for LISP multicast over Native multicast. The motivation for the TLV and the problem statement can be explained in an email to LISP WG. As suggested, this can be considered as a topic of discussion for the upcoming LISP WG interim. Can you please share the date(s) ?
Actually we have no interim meeting planned, I was referring to IETF 111 :-)


> On a separate note, it was discussed that this draft should be progressed in the PIM WG but after the LISP WG is convinced about the genuineness of the problem statement and the proposed solution. Stig pointed out during the IETF PIM WG discussion, that RFC8059 was progressed in a similar way.

Sure. The LISP WG can provide feedback on the LISP part, and it is a very good idea to have some discussion in the LISP WG.
Then, the document can progress in the PIM WG, since it does not involve any specific change in LISP.
