I don't remember why, but if I had to guess, it was probably because I had obtained the assignment of the the IP Protocol number for IGMP from Jon Postel, but didn't think I could justify, to Jon's satisfaction, getting another Protocol number or well-known UDP port number for what was just a grad-student's experimental protocol. Similarly, extending the RIP specification probably seemed above my pay grade. So, likely no architectural reason, just a convenience at the time.<br></blockquote><div><br></div><div>My vague memory is that you thought it was a positive thing, architecturally good, to keep them together. </div><div><br></div><div>Scott</div></div></div></div>
