Hello Pascal,

I have a comment about multicast protocol in draft-ietf-roll-unaware-leaves-02:

Section 8 explains Protocol Operations for Multicast Addresses and lists Registration flow of MLDv2.
RFC7731 MPL is also a popular Multicast Protocol for Low-Power and Lossy Networks.

Is it possible to add any description for MPL? Such as:

  *   RUL should not be a MPL forwarder
  *   MPL Hop-by-Hop Header can be ignored when not understood
  *   6LR might decapsulate MPL’s IP-in-IP packet and forward to RUL


Best regards,
Li
