7. Bandwidth vs Clock Rate and Speed In the next lecture you’ll learn about how the OSPF cost metric works and how it’s based on interface bandwidth by default. But before we get there, I want to explain how the bandwidth command works and what it does and how it relates to the speed and […]

4. OSPF Basic Configuration Lab Demo In this lecture, you’ll learn how to do a basic configuration of OSPF on our Cisco routers. So to enable OSPF, the top level command at Global Config is router OSPF and then a process ID. So you can see an example here. I’ve said router OSPF One. Different […]

1. Introduction Section, you’ll learn about the last of our IGPs, our interior gateway routing protocols for the CCNA exam. That’s OSPF, the open, shortest path first protocol. We’ll start with a description of the characteristics of OSPF, and then we’ll move into doing basic configuration. After that, we’ll cover some more advanced topics like […]

4. Layer 3 Switch Learn about the third and last option for interval and routing, which is to use a layer three switch. Now you’re less likely to get tested on this option in the CCNA exam, but it’s actually the option which is most commonly used in the real world. So I wanted to […]

1. Introduction Section, we covered all of the layer two configuration for VLANs, but when we left off, our clients that were in different VLANs weren’t able to communicate with each other at layer three, so you’ll learn how to do that. In this section, there are three different options you can use for your […]

4. EIGRP – the Enhanced Interior Gateway Routing Protocol You’ll learn about the characteristics of EIGRP, and we’ll do a basic configuration as well. So EIGRP stands for the Enhanced Interior Gateway Routing Protocol. Its predecessor was iGRP, but that’s a really old legacy protocol. It’s not used anymore. EIGRP is great protocol, sports large […]

1. Introduction In this section you’ll learn about rip and EIGRP. It’s actually OSPF, which is the main focus of the CCNA exam as far as routing protocols are concerned. But you are still expected to know the fundamentals of rip and EIGRP, so we’re going to cover them here. You’re not going to need […]

1. Introduction Section, you’ll learn about Cisco support for DHCP. DHCP is the Dynamic Host Configuration Protocol, and it’s a way that we can automate assignment of IP addresses on our host. It’s much quicker to use DHCP and more convenient than it is to manually assign IP addresses to everything. In this section, I’ll […]

1. 7.1 Create and manage date-based and time-based events Hello everyone. In this lesson, we will focus on the first item of the Use Java Se Eight Date Time API topic and the Javas Eight Programmer Two Exam Syllabus that is creating and managing date based and time based events, including a combination of date […]

1. 4.1 Use the built-in interfaces included in the java.util.function package such Hello everyone. In this lesson we will focus on the first item of the lambda builtin functional interfaces topic in the Java Se eight programmer two exam syllabus that is using the builtin interfaces included in the Java Util function package such as […]
