Description

Many engineers work their whole careers without ever really looking under the hood to understand why a network was designed the way it was. Some of this is because their day to day duties don't require this knowledge and some of this is because an engineer chooses to focus their knowledge on becoming exceptional operational engineers. This course, Enterprise IP Routing Design for CCDA DESGN (200-310), will take a closer look at the routing protocols that are commonly implemented in Enterprise networks, specifically covering EIGRP, OSPF, IS-IS and BGP. You'll begin with a review the basics of routing protocols including the different types and behaviors that are common between them. You'll first learn about EIGRP, including a review of the basic EIGRP concepts including neighborships, metrics, the topology table, summarization, and stub. Next, you'll explore IS-IS, including a review of the basic IS-IS concepts including neighborships, metrics, and areas. Finally, you'll get to learn about BGP, which includes a review of the basic BGP concepts including neighborships or peerings, and path selection. When you are finished with this course, you'll have a firm base of understanding of the different routing protocols that are commonly implemented in an enterprise environment.

Course Overview
Welcome to Pluralsight. My name is Sean Wilkins, and I am a network engineer, author, and technical editor at infoDispersion. I'm excited to welcome you to my course, Enterprise IP Routing Design for CCDA DESGN. This course is one of many courses that are being introduced into the Pluralsight library to cover networking design. This course specifically is targeted on the common routing protocols that are implemented on enterprise networks, as well as an overview of how they compare against each other. The modules that we will cover include common IPv4 and IPv6 routing concepts, including the different types and behaviors that are common between routing protocols. Enterprise EIGRP design, including neighborships, metrics, and the topology table. Enterprise OSPF design, including neighborships, metrics, areas, and nulling state database. Enterprise IS-IS design, including neighborships, metrics, and areas. And enterprise BGP design, including peerings, attributes, and path selection. By the end of this course, you will have a firm base of understanding of the different routing protocols that are commonly implemented in an enterprise environment. Before beginning this course, you should be familiar with networking fundamentals, including IPv4 and IPv6 addressing, and an understanding of how networking devices interconnect together. After viewing this course, you should feel comfortable diving into other networking design courses on Campus Edge design, Enterprise Data Center design, Enterprise Campus design, and Enterprise IP and IPv6 addressing design. I hope you'll join me on this journey to learn networking design with the Enterprise IP Routing Design for CCDA DESGN course at Pluralsight.

Enterprise EIGRP Design
Hello everyone, and welcome to Enterprise Campus Design for CCDA DESGN. My name is Sean Wilkins, and this is the Enterprise EIGRP Design module. In this module, we are going to be building on the last module, and discuss one of the most popular routing protocols, EIGRP. EIGRP has been around for a long time, and has proven to be a very reliable, easy-to-configure protocol that does its job without much fuss. This module will review some EIGRP basics, including common operational details about how it fits against other routing protocols. We'll then discuss details about how EIGRP uses neighborships. Then we move on to discuss the often confusing EIGRP metric, before we get a little more detailed and talk about how EIGRP exchanges routes and creates a topology table before inserting routes into a device's main routing table. We then discuss how summarization and the EIGRP stub feature can be used to optimize the way that EIGRP operates, before we go into a number of general recommendations to follow when designing a network using EIGRP. And finally, we will finish up with a section on the Globomantics network that has been used across the CCDA courses. So now with all this out of the way, let's get started.

Enterprise OSPF Design
Hello everyone, and welcome to Enterprise Campus Design for CCDA DESGN. My name is Sean Wilkins, and this is the Enterprise OSPF Design module. In this module, we are going to continue building on the previous modules and discuss another popular routing protocol, OSPF. OSPF, like EIGRP, has been around for some time. Some engineers hate it, and some love it, but it has a number of benefits that make it an appealing choice regardless of the situation. This module will review some OSFP basics, including common operational details about how it fits against other routing protocols. We will then discuss details about how OSPF uses neighborships, including a discussion about network types and neighbor states. We then move on to discuss the OSPF metric. Next we move on to a review of OSPF areas and router types, before moving onto a discussion of the OSPF database, including covering the different LSA types that are used by OSPF. We then discuss OSPF stub areas and OSPF summarization options, and then wrap up the module with a section on some high-level recommendations that could be used when building an OSPF network, and a section on how OSPF can be used on the Globomantics network. So now with all this out of the way, let's get started.

Enterprise IS-IS Design
Hello everyone, and welcome to Enterprise Campus Design for CCDA DESGN. My name is Sean Wilkins and this is the Enterprise IS-IS Design module. In this module, we are going to continue building on the previous modules, and discuss another routing protocol, IS-IS. IS-IS has been around for some time, just like EIGRP and OSPF, but it is not as popular. Generally speaking, you will not see IS-SI implemented in many enterprise networks outside of a data center environment. This is mainly due to many network engineers not having a familiarity with the protocol, and thus having much less confidence in implementing, or frankly having a reason to implement it over other much more familiar options. It is, however, much more popular in service provider environment. This module will review IS-IS basics, including common operational details about how it fits against other routing protocols. We will then discuss how IS-IS uses neighborships, including a discussion about network types and states. We then move on to discuss the metric used by IS-IS. We then move onto a discussion about how areas, or flooding domains, are used by IS-IS to organize a network, before wrapping up with a section on some high-level recommendations that could be used when building an IS-IS network, and finally, a section on how IS-IS could be used on the Globomantics network. So now with all of this out of the way, let's get started.

Enterprise BGP Design
Hello everyone, and welcome to Enterprise Campus Design for CCDA DESGN. My name is Sean Wilkins, and this is the Enterprise BGP Design module. In this module, we are going to move on from our coverage of interior routing protocols, and discuss the only real exterior routing protocol in use on today's networks, the border gateway protocol, or BGP. BGP has been around for a long time, and has long been used as the backbone of the modern internet, both with IPv4 and IPv6. It has also been expanded to be used for a number of different purposes across the network, from using it on parts of the interior of enterprise networks, to using it along with popular virtual private networking solutions. For this module, our focus will be on its use in the enterprise environment. This module is split into the following sections. The first section will cover the basics, including reviewing the different types of BGP, including its interior and exterior variations, as well as a review of the different BGP message types. Next we will move on and cover details about BGP peerings, also referred to as BGP neighbors. In this section, we will discuss the different peering types, neighborship states, and common topologies. We then cover the BGP path attributes, as well as review of the basic BGP path selection process should multiple matching prefix entries exist. We then finish this up with short sections on BGP general recommendations, as well as some recommendations for BGP use in the Globomantics network. So now with all of this out of the way, let's get started.
