Juniper launches Design Certification Track

This tweet from @JuniperCertify has caught my attention: It's official...the Design track released today! Details: Insights from a JNCDA developer: — Juniper Networks Certification Program (@JuniperCertify) May 27, 2015 Later that day, I got an e-mail from Juniper with the same announcement. Juniper has launched its Design Certification Track inside the Juniper Networks Certification Program (JNCP) and the Juniper Networks Certified Design Associate (JNCDA) is the first available certification.

Juniper publishes vMX

This tweet from @JuniperNetworks has really inspired me yesterday. I liked Junipers Firefly Perimeter (vSRX) from the first day. I like the idea behind this product (yes, I like everything that can be run as a VM…). But yesterday Juniper has go one better. Introducing the vMX – the industry's only carrier class virtualized router: #networkunlocked — Juniper Networks (@JuniperNetworks) November 6, 2014 Juniper Networks announced yesterday a virtualized and carrier-grade version of their MX Series 3D router.

Exam experience JNCIA-Junos

The Juniper Networks Certification Program (JNCP) consists of different tracks, which enable you to demonstrate your skills with Juniper products and technologies in the areas most pertinent to your job function and experience. There are three main areas: Junos Support Product and Technology The Junos area consists of three tracks: Service Provider Routing and Switching Enterprise Routing and Switching Junos Security The “Service Provider Routing and Switching” track focuses on service provider and telecommunication (M-, MX-Series, Routing with OSPF, BGP, MPLS etc.

My lab network design

Inspired by Chris Wahls blog post “Building a New Network Design for the Lab”, I want to describe how my lab network designs looks like. The requirements My lab is separated from my home network, and it’s focused on the needs of a lab. A detailed overview about my lab can be found here. My lab is a lab and therefore I divided it into a lab, and an infrastructure part.

Juniper SRX: Using CoS to manage bandwidth

Sometimes it’s necessary to limit specific traffic in terms of bandwidth. Today I like to show you how to manage bandwidth limits using QoS and firewall policies. Especially if you have only limited bandwidth, e.g. a DSL connection, it can be useful to manage the used bandwidth for specific hosts or protocols. I use a really simple setup to show you, how you can manage bandwidth using CoS on a Juniper SRX.

Configuration management with Juniper Junos

One strength of Juniper Junos is the config file management. The concept of different configurations is nothing special. For example Cisco uses two configuration files to reflect the current configuration in the RAM (running configuration), and the configuration used on startup (startup configuration). HP is doing the same on their networking gear. If you are new to Juniper Junos, the concept of an active configuration and a candidate config, which holds the current changes but isn’t active, maybe confuses you.

Juniper Firefly Perimeter

I’m a big fan of Juniper Networks! I work mainly with the SSG (ScreenOS) and SRX (Junos) series. The Juniper SRX is a network security solution, which can be positioned in the data center or at the branch. You will surely agree, that virtualization and cloud computing changed a lot from the network perspective. This demands security solutions that are not bound to hardware boundaries. Juniper Firefly Perimeter addresses this demands.
