No, neither IGRP nor EIGRP are open standards. They are Cisco 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.
