DISCUSS:

In section 9 (security considerations):
Thanks for discussing network load here! However, I find this sentence a bit
unsatisfactory:
   „The specification of counter-measures for this problem is outside the scope
   of this document.“
Isn’t there any easy way to make some more recommendations for counter measures
that could be discussed here? E.g. implement some rate limiting or filtering.
Or only accept LIR-PF request from preconfigured hosts (given that LIR-PF
support must anyway be pre-configured)? I’m not an expert on this topic and
therefore don’t know if any of such recommendations make sense, however, I
would quickly like to discuss if it is potentially possible to say more than
what’s current said. Thanks!

Some other minor comments:
 1) section 2: „Use of this flag in the PTA carried by other route types is outside
   the scope of this document.  Use of this flag in the PTA carried by
   an S-PMSI A-D routes whose NLRI does not contain a wildcard is
   outside the scope of this document.“
Maybe you also want to say something like „The flag SHOULD be ignored in these cases.“..?

 2) section 3
s/The result (if any) is the match for tracking“/The result (if any) is the “match for tracking“/
(missing quotes)
