This is not backwards compatible with RFC 3344 which supports GRE tunneling, which is established by setting the G bit w/o GRE Key Extension.

 

   “If the HA receives a Registration Request with the 'G' bit set but

   without the GRE Key Extension, it SHALL send an RRP with code 'Poorly

   Formed Request (0xY2)'.”
