Im saying so with the logic that Application Layer itself suggests "Human readable form" after going through the Presentation Layer which gives the format for it. I think that they should be just termed as Transport Layer protocols if you really want to term it in OSI form.

That's why these are combined in the IP model. Since they rely on another transport protocol, they aren't the same as OSPF and EIGRP. I would definitely say BGP and RIP are protocols that run in the application layer. -- Regards, Rick Mur CCIE2 #21946 (R&S / Service Provider) Juniper JNCIA-ER & JNCIA-EX MCSA:Messaging, MCSE Sr. Support Engineer – IPexpert, Inc.

Only because they use the Port-numbers for identicification & that EIGRP, OSPF, ISIS etc dont? Transport Layer is Port numbers [in a very raw sense]. What Presentation Layer protocol does BGP & RIP use? And What Application Layer thing are we talking about for running them?? I personally think its just a sham to write these Protocols off as Application layer Protocols. ----- Original Message ----- From: "Dale Shaw" To: "Taqdir Singh" Cc: [email protected] Subject: Re: [OSL | CCIE_RS] RIP and BGP are application layer protocol Date: Wed, 19 Aug 2009 17:07:07 +1000 Hi, On Wed, Aug 19, 2009 at 4:58 PM, Taqdir Singh wrote: > TCP and UDP are transport layer protocols.

Both RIP and BGP are applications and therefore have an application layer. The transport layer protocol employed is largely irrelevant.
