wouldn't be the first time Doyle said something incorrect in his book. ;->
sorry, I'm not trying to pick a fight with you in particular. I've been round the block more than once at various voice volumes with people on this list about "what layer" this and that operates at. I've also been round the block a few times regarding "authority" My own reading of the RFC's has convinced me that the authors had something far different than "layers" in mind when they were discussing and designing the various protocols. In many cases, IMHO, they are looking at things in terms of a data processing model, or a software flow chart kind of model. When I took my first MIS class in the early 80's, the text compared the OSI and the SNA models side by side. We've come a long way since then. We no longer have to memorize the SNA model. :-> cheers Chuck -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Tribavan Raina Sent: Wednesday, September 26, 2001 6:37 PM To: [EMAIL PROTECTED] Subject: RE: which layer BGP,RIP ,OSPF work on [7:21226] My intention of creating this thread again was just to clarify things as some of us concluded that BGP,RIP,OSPF are at network layer. Why I quoted the stuff in capital and if it hurt some of the members ,I am sorry but it was just to highlight that this is given in Cisco Press book and whose author is CCIE and ofcourse reviewed by Imran Qureshi Program Manager from Cisco on CCIE series of books. So again is it right that 1)RIP,BGP are at application 2)OSPF is at Transport layer Regds Tribavan -----Original Message----- From: Mark Morenz n[mailto:[EMAIL PROTECTED]] Sent: Wednesday, 26 September 2001 4:42 p.m. To: [EMAIL PROTECTED] Subject: Re: which layer BGP,RIP ,OSPF work on [7:21226] The OSI model is relatively important (why else would questions about it routinely become the longest threads?). My whole argument for them is this: Models are just learning tools. When people learn biology, they don't *start* by learning "how things work", they *start* by learning the major systems (skeletal, neuro-muscular, etc.). That's all the model-- ANY model-- should be about. I agree that the arguments tend to get esoteric. But some spirited debate never hurts. :-{)] Mark A. Morenz, MS Ed, CCNA, CCAI From: dre [mailto:[EMAIL PROTECTED]] Sent: Wednesday, 26 September 2001 2:28 p.m. To: [EMAIL PROTECTED] Subject: Re: which layer BGP,RIP ,OSPF work on [7:21226] The OSI model clearly needs to be replaced by something else. It is by far the most abused/misused way of describing networking concepts and ideas. If the OSI model helps you plan/design, install, support/administer any network idea/concept/technology -- all the better. If you spend your waking hours thinking how every network idea/concept/technology fits into the OSI model, there is something clearly wrong with you. And IMO, I personally think that tests should not include anything about the OSI model. It's important to know it, but there are much greater things to know in networking like protocol specifics. I'd much rather know how OSPF/RIP/BGP work than what layer they 'primarily' function on. Also, please try to refrain from using all capital letters when making stupid posts that are meaningless to this list. -dre -----Original Message----- From: Tribavan Raina [mailto:[EMAIL PROTECTED]] Sent: Wednesday, 26 September 2001 2:03 p.m. To: [EMAIL PROTECTED] Subject: which layer BGP,RIP ,OSPF work on [7:21226] Hi all.. The answers which we got for this question were wrong.I consulted the CISCO PRESS BOOK JEFF DOYLE ROUTING TCP/IP 1)RIP,BGP ARE AT APPLICATION LAYER ,PAGE 31 CHAPTER GUESS 1OR 2. 2)OSPF AT TRANSPORT.
