Ron, Your draft recommends that the ingress node discards the frame and sends ICMP msg to the source node when the size of GRE encapsulated frame exceeds link MTU. We experienced that Window XP doesn't adjust frame size after receiving ICMP message. Many Linux based applications don't do anything either with the MTU ICMP message. I think your draft should point those issues out and recommend fragmentation approach under those circumstances.
