It's a nice little protocol, if a bit limited.

This was apparently an IGRP cversion created to the ISO CLNS specifications.

Re: IGRP as proprietary? [7:57603]
Depends on your definition of "open standard". As far as I can tell there are no RFC's for IGRP or EIGRP, which is pretty much the criteria for something to be considered an "open standard" in the Internet community. Also, I don't believe Cisco has released the source code for either IGRP or EIGRP. Based on that, I would consider both routing protocols to be proprietary. I believe some non-Cisco companies have interoperable implementations of IGRP, but my guess would be they either reverse engineered it or paid Cisco for the code. In short, by most definitions, IGRP/EIGRP would be considered proprietary.

There are no RFCs or other industry-standard specifications that document the protocols. With IGRP, Cisco did allow Rutgers University to publish a good article that explains everything you need to know about IGRP. See here: http://www.cisco.com/warp/public/103/5.html With EIGRP, it would be much harder to figure out exactly how it all works unless you were a Cisco IOS software developer. But Cisco TAC does have some good Web pages about EIGRP. See here: http://www.cisco.com/warp/public/103/eigrp-toc.html So... with these documents, theoretically another company could gather enough info to implement IGRP and EIGRP. But legally Cisco wouldn't allow this without some sort of licensing agreement. Cisco owns the technology, in other words. The protocols are proprietary, even though Cisco doesn't seem opposed to publishing info on how they work. Cisco's motivation for publishing info is to help network admins use Cisco's implementations, not help a competitor (or even a collaborator) do their own implementation. ___ Priscilla Oppenheimer www.troubleshootingnetworks.com www.priscilla.com > > I would like to verify on this.

AW: IGRP as proprietary? [7:57603]
I always thought that EIGRP was cisco proprietary but IGRP was not. I did find the below on the ietf site which makes me think that at least in 96 it was not standard. I think it has been industry standard since 98 though stuart IGRP is a proprietary protocol of Cisco, and Cisco believes at this time, that the proposed submission violates Cisco's rights in the protocol and in the trademark. Therefore, Cisco believes the internet draft should not be published. -Urspr|ngliche Nachricht- Von: hktco [mailto:[EMAIL PROTECTED]] Gesendet am: Monday, November 18, 2002 12:39 PM An: [EMAIL PROTECTED] Betreff: IGRP as proprietary?
