Hi Dirk, many thanks for carefully looking through the draft. Please see comments inline.

The update of 5568 is with the PrRtAdv-Messages. 5949 does not contain such things, as there is no explicit messaging between MAGs and the MN.

Protocol Operations Specific to PFMIPv6" and Figs. 4/5 do include "PMAG (PAR)" and "NMAG (NAR)" - isn't it all about PMIP - so no relevance for AR?
