Thanks for the answer. I am still a bit concerned that a reader will be
slightly confused, though. Can I suggest trying to rephrase the sentence
a bit, something like:

OLD:
   A mechanism,
   similar to as described in [I-D.weis-gdoi-mac-tek] can be used to
   distribute group keys to a group of ISes in Level-1 area or Level-2
   domain, using GDOI as specified in [RFC6407].

NEW:
   A mechanism is needed to distribute group keys to a group of ISes
   in a Level-1 area or Level-2 domain, using the Group Domain of
   Interpretation (GDOI) protocol as specified in [RFC6407]. An example
   policy and payload format was described in [I-D.weis-gdoi-mac-tek].

Regards
    Brian
