By now, you should have an idea of how routing works and whether we use static routes, default routes, or dynamic routing protocols. We have already configured EIGRP for IPv6, but we did not get into the details for this unique routing protocol.
One of the more confusing questions is: Are the EIGRP routing protocols still proprietary to Cisco? Not any more! For more information on open standard EIGRP used by multiple vendors, refer to the following link: http://tools.ietf.org/html/draft-savage-eigrp-00
It's not only a challenge for real-world networks and their devices, but what about the CCNA certification exam? How do we answer that question, if asked? As far as the CCNA 200-125 is concerned, EIGRP still remains proprietary to Cisco, and that is the way you must think and answer in the exam.
In the real world, that will be completely...
