Series Introduction

Transcript - Series Introduction    Series Introduction You may have found yourself in the same situation as I was in a year ago. I’m familiar with Cisco equipment, but I suddenly found myself needing to support Juniper devices. While the core networking principles are the same, the configuration and troubleshooting methods are sometimes quite...

CLI Introduction

Transcript - CLI Introduction  Quiz Page: https://networkdirection.net/labsandquizzes/quizzes/juniper-jncia/cli-introduction Lab Page: https://networkdirection.net/labsandquizzes/labs/jncia-labs/cli-introduction Introduction Welcome to video 2 of our Introduction to Juniper series. We’re going to look at the basics of the Juniper CLI, as well as the configuration hierarchy. CLI Modes Juniper devices run the Junos operating system. Junos can be configured through the CLI or the...

VLANs and Interfaces

Transcript - VLANs and Interfaces    Quiz Page: https://networkdirection.net/labsandquizzes/labs/jncia-labs/vlans-and-interfaces Lab Page: https://networkdirection.net/labsandquizzes/labs/jncia-labs/vlans-and-interfaces   Introduction There’s no point having a network device without interfaces. In this video, we’re going to take a look at both physical and virtual interfaces.   Interface Types Firstly, if we want to see a list of our interfaces, use show interfaces terse....

DHCP

Transcript - DHCP    Quiz Page: https://networkdirection.net/labsandquizzes/quizzes/juniper-jncia/dhcp Lab Page: https://networkdirection.net/labsandquizzes/labs/jncia-labs/dhcp   Introduction DHCP is essential in most networks. We might have a dedicated DHCP server at a large office, but smaller offices can benefit from DHCP running on a local router or switch. And that’s exactly what we’re looking at here. Running a DHCP server or...

Active and Candidate Configuration

Transcript - Active and Candidate Configuration    Quiz Page: https://networkdirection.net/labsandquizzes/quizzes/juniper-jncia/active-and-candidate Lab Page: https://networkdirection.net/labsandquizzes/labs/jncia-labs/active-and-candidate   Introduction Welcome to part 2 of the Introduction to Juniper series! In part 2, we’re focusing on device configuration at a deeper level. We’re kicking off in this video by looking at the active and candidate configurations. Active and Candidate Juniper has...

Configuration Rollback

Transcript - Configuration Rollback    Quiz Page: https://networkdirection.net/labsandquizzes/quizzes/juniper-jncia/configuration-rollback Lab Page: https://networkdirection.net/labsandquizzes/labs/jncia-labs/configuration-rollback   Introduction Juniper keeps a bunch of config backups, but how do we use them? In this video, we’re looking at how to rollback our changes and restore backups.   Commit Confirmed The commit model is probably my favourite Junos feature. But we’ve only seen...

Configuration Groups

Transcript - Configuration Groups    Quiz Page: https://networkdirection.net/labsandquizzes/quizzes/juniper-jncia/configuration-groups Lab Page: https://networkdirection.net/labsandquizzes/labs/jncia-labs/configuration-groups   Introduction If we apply similar config in multiple places, to interface configuration for example, there are a few tricks we can use. One trick is Configuration Groups, which is a block of reusable config.   Creating and Applying Groups On occasion, we might need...

Authentication

Transcript - Authentication    Quiz Page: https://networkdirection.net/labsandquizzes/quizzes/juniper-jncia/authentication Lab Page: https://networkdirection.net/labsandquizzes/labs/jncia-labs/authentication   Introduction Juniper devices can have local usernames and passwords. But if we have a lot of devices, this can be hard to manage. That’s why it’s often beneficial to configure external authentication, such as RADIUS or TACACS.   Local Logins But let’s start with local...

A New Device (Part 1)

Transcript - A New Device (Part 1)    Quiz Page: https://networkdirection.net/labsandquizzes/quizzes/juniper-jncia/a-new-device Lab Page: https://networkdirection.net/labsandquizzes/labs/jncia-labs/a-new-device   Introduction We’re taking a different approach in this video. We’re going to go through a scenario where we’ve been given an old EX2200 series switch, which works fine, but needs to be set up.  We’re going to reset it, and then...

A New Device (Part 2)

Transcript - A New Device (Part 2)    Quiz Page: https://networkdirection.net/labsandquizzes/quizzes/juniper-jncia/a-new-device Lab Page: https://networkdirection.net/labsandquizzes/labs/jncia-labs/a-new-device   Introduction In the last video we started configuring a small switch from the ground up. Now, we’re going to finish off the config, and include a few tricks that you can use.   Basic Config We’re getting back into it by...

Platforms

Transcript - Platforms    Introduction Welcome back to part three of this video series, where we will look at hardware and software architecture. Juniper likes to keep Junos consistent across all their platforms, which is a pleasant change from some of the competitors. In this brief video, we’ll see some of the platforms that...

Junos Architecture (Control and Data Planes)

Transcript - Junos Architecture (Control and Data Planes)    Quiz Page: https://networkdirection.net/labsandquizzes/quizzes/juniper-jncia/architecture-planes Lab Page: https://networkdirection.net/labsandquizzes/labs/jncia-labs/junos-architecture-planes   Introduction You’ve probably heard about the control and data planes before. Juniper was one of the companies that pioneered these concepts, and they do an amazing job of putting it into practice. This video will discuss what these planes are,...

Junos Architecture (Processes)

Transcript - Junos Architecture (Processes)    Quiz Page: https://networkdirection.net/labsandquizzes/quizzes/juniper-jncia/architecture-processes Lab Page: https://networkdirection.net/labsandquizzes/labs/jncia-labs/junos-architecture-processes   Introduction There are different schools of thought when it comes to operating system design. Juniper’s Junos and Cisco’s IOS for example, take very different approaches. We’re going to see the advantages to Junos’ modular design.   Monolithic and Modular Operating Systems When it...

Firewall Filters

Transcript - Firewall Filters    Quiz Page: https://networkdirection.net/labsandquizzes/quizzes/juniper-jncia/firewall-filters Lab Page: https://networkdirection.net/labsandquizzes/labs/jncia-labs/firewall-filters   Introduction Firewall filters are like ACLs. They’re used to match traffic, and perform an action. In the most obvious case, this acts as a packet filter, or stateless firewall. But they can be used for other things too, like routing policies and Quality of...

Routing Table

Transcript - Routing Table  Quiz Page: https://networkdirection.net/labsandquizzes/quizzes/juniper-jncia/routing-tables Lab Page: https://networkdirection.net/labsandquizzes/labs/jncia-labs/routing-table Introduction Welcome to part 4 of the Introduction to Juniper series, which is all about routing! We’re starting, right here, with the routing table. Routing Tables We often talk about the ‘routing table’ like there’s only one. The truth is, there are several routing tables in...

Routing Instances

Transcript - Routing Instances    Quiz Page: https://networkdirection.net/labsandquizzes/quizzes/juniper-jncia/routing-instances Lab Page: https://networkdirection.net/labsandquizzes/labs/jncia-labs/routing-instances   Introduction Occasionally, we need to separate one type of traffic from another. Perhaps because the traffic belongs to different customers, or one type is less secure. One method of doing this is by creating additional routing tables, which prevents the traffic routing outside of...
