Implementing EIGRP for CCNP Routing and Switching 300-101 ROUTE

Route Redistribution: EIGRP, OSPF, and RIP
So far we've covered the basics of EIGRP's operation and how to configure EIGRP for IP Version 4. In this module we're going to delve into some more advanced EIGRP configurations involving route redistribution between EIGRP and OSPF and EIGRP and RIP. Before we get started I want to offer a tip to help you get the most out of this module. Nobody, and I mean nobody, with maybe the exception of a super genius fully comprehends or remembers everything about networking the first time they learn it. I absolutely do not expect you to walk away from this course having memorized every last detail and command that we're going to use. Repetition is the mother of learning and you must repeatedly study and practice these configurations if you're going to pass the CCNP ROUTE exam. Since you're likely going to be watching this module more than once, I've broken it down into clips covering specific topics and configurations. First, we're going to discuss the concept of mutual route redistribution. Next, we'll redistribute EIGRP into OSPF and then OSPF into EIGRP. Next we'll talk about redistribution loops and finally we'll finish out by redistributing RIP into EIGRP.

Route Redistribution: Manipulating Traffic Flow
In this module we're going to take redistribution a step further or maybe two or three steps further. We've already redistributed routes among EIGRP, OSPF, and RIP. But, up to this point we've just let the routing protocols determine how traffic is forwarded. Now it's time for us to learn how to manipulate the IP routing table to drive traffic the way our customer wants it to go. We'll start off by performing both equal and unequal cost load sharing. Next we'll modify administrative distances, configure route filtering, and finally learn how to advertise default routes into EIGRP.

Implementing EIGRPv6 for IPv6
The CCNP ROUTE objectives call for you to configure and verify EIGRP for IPv6, and that's it. So if you are worried about having to perform all of the previous EIGRP configurations with IPv6 instead of IPv4, you can breathe a sigh of relief because this module is going to be a bit shorter. So let's talk about the differences between EIGRPv4, which is what we've been using with IPv4 and EIGRPv6 for IPv6 of course. EIGRPv6 is enabled on the individual interfaces, which means the network command is not used. Distribute lists with EIGRPv6 must use prefix lists. No ACLs, no route maps. Also, since IPv6 is classless, there is no automatic summarization feature even available in EIGRPv6. EIGRPv4 uses the multicast address 224. 0. 0. 10 while version 6 uses the IPv6 multicast address FF02::A and if you know your hexadecimal, A is 10 in decimal. And believe it or not those are main differences between version 4 and version 6 that you need to know for the exam. So with all that out of the way, let's get to our first customer request for EIGRPv6.
