Dear all,

I have some doubts/comments on 
draft-krishnan-multimob-pmip6basicmcast-solution-00, specifically:

1/ LMA will receive the membership report messages from the MNs with 
source address the MN's link-local address. Nevertheless, the MN's 
link-local addresses are not part of the binding cache as defined in 
RFC5213 (sections 5.1 and 6.1). My question is how the LMA can build 
the relationship between MN link-local address and MN-HoA to be able to 
generate the message stated in figure 2?

2/ If two or more MNs have the same link-local address, how can the LMA 
distinguish among MN membership report messages entering the LMA with 
the same source addess through the same MAG? Could this situation 
produce that every new group suscription query coming from one of such 
MNs applied for all of them due to the fact that they have the same 
source address?

Thanks in advance,

best regards,

Luis
