Hello, I've some questions about transporting frame relay over IP (I know, the world is getting crazy): 1. Does anybody have any experience with encapsulation of frame relay by means of GRE with IPv4 as delivery protocol (RFC1701, 1702, 2784)? 2. Why shouldn't I try to transport FR (FRF1.1) over IP? What are the cons? 3. Does anybody know, why the sequence number has been deprecated in RFC 2784? 4. Are there any vendors which implement GRE according to the latest RFC 2784?
