From IOS to Junos Series - Foreword

IOS to JUNOS challenge

I have set myself a small challenge of obtaining JNCIA-Junos in the next few week. To assist in achieving this to supplement the study material on the Juniper web site, I have set myself up a small lab environment using VMWare EXSi 5.0 Hypervisor and Juniper Olive (JUNOS 10.1). I got great help from

I currently have the following at my disposal from the Juniper web site:

  • JNCIA-Junos_SG_part_1_09-16-2010.pdf

  • JNCIA-Junos_SG_part_2_09-16-2010.pdf

I also bought two kindle books

  • JUNOS Enterprise Routing [Kindle Edition] By: Doug Marschke, Harry Reynolds

  • JUNOS Enterprise Switching [Kindle Edition] By: Doug Marschke, Harry Reynolds

The exam blue print can be found here

I hope to tick these off as I work through my lab. I have quickly written the following objects for myself which I will expand as I progress on my journey.

  • Host Name

  • Management IP

  • Time

  • User (admin and read only)

  • SNMP

  • SSH

  • Telnet


  • Syslogging

  • Basic routing RIP - Junos1 to Junos2

  • Basic Routing OSPF - Junos 2,3,4,5

  • Basic Routing BGP - Junos 4,5

  • Access List - Protect SSH access, routes filters

  • VLAN ??

  • IP Helper???

  • VRRP ???

My Hardware

HP ML110 G6 , 8 GB Memory, 3 Hard disks (250GB), 2 X 1GB no RAID (couldn't get it to work)

ESXi 5.0. Tip for installation, use the integrated remote management console and virtual media to boot from the ISO image. The CD drive in the system is SATA attached and VMWare ESXi 4.1 did not find the device during installation, I didn't even both when upgrading to 5.0.


The Journey is more important that the destination

This is a journey from me, the end goal is a bonus. At this point all I have done on Junos is set and IP address and check ping connectivity so I have no idea how this series is going to go, or what sort of learning point it is going to throw up comming from a Cisco background. The ultimate goal is to progress beyond JCNIA-Junos, but I don't want to get ahead of myself.

Watch this space for Updates.........



  1. Hi,

    I'm just about to do what you're doing. I've recently gotten my CCNP and am now
    getting the vibe, when looking for a new job, that some JunOS knowledge is not
    a good thing, but a necessary thing to have. :-)

    So I just got me a olive setup (using GNS3) and am now reading "JunOS for dummies"
    (terrible book) and "JunOS cookbook" (seems to be better so far) to get the JNCIA and
    hopefully the JNCIS if time permits.

    I'll follow your progress closely. :-)

Break the Network Emulators out of the Cloud

Cisco IOU and JunoSphere Recently both Cisco and Juniper have announced the availability of online resources to provide hands on training over the internet. They have built software emulators in the cloud that can be accessed remotely for a cost. These solutions are based purely around the certification programs and therefore are pretty rigid in the topology that are provided, not to mention the re-occurring cost. Rack Rentals There are training providers such as Internetwork Expert ( and IPexpert ( who provide rack rentals based on their training materials. These guy cannot possibly compete going forward. To keep these sustainable they will need to reduce the overhead of building physical racks, providing power and space for the racks. Using e

Dell Latitude D830 SSD Upgrade

Slow Laptop Syndrome I have a LATITUDE D830 : INTEL CORE 2 DUO T7500 4GB Ram from 2008, I did get a fairly high specification at the time, so it has always had pretty decent performance. However I haven't been using it for a while and when I did it seemed slow compared to my Core 5i desktop computer. (I use Windows 7 ultimate with the latest updates) Laptop for Work Now I might be doing a fair bit of travelling to customer sites in the near future and the last thing I want is a poorly performing Laptop, so I decide to ditch all the crap I had on it like iTunes, movies, miscellaneous software and cut back to a basic "work" PC. After all I do have iPhone, iPad and new kindle (soon) for all my multi media needs. I purchased a "Corsair 120GB Force 3 SSD 2.5" SATA-III 6Gb/s Read = 550MB/s, Write = 510MB/s" from Now I am guessing that SATA-II rather that SATA-III on the system board, but the price difference between SATA-II and SATA-III wa

ASR1006 Dual Route Processors Password Recovery - Tip

I recently ran into an issue when trying to perform dual route processors password recovery on a Cisco  ASR1006 Problem After breaking into rommon mode and using confreg to ignore the startup configuration, during the rest the ASR1006 loaded the startup configuration!!!!!!!! Solution So quick and simple, I pulled one of the RP and preformed password recovery running on a single RP. All went according to the Cisco documentation   After the system running on a single RP was recovered and fully booted I waiting for 5 minutes just to be sure; then I inserted the second RP and allowed everything to sync up.   All was well again :) phew   Note: The system was previously fully functioning with dual RPs; a configuration error was made during Tacacs+ configuration which resulted in lockout.   Summary I hit an issue recovering and ASR with dual RPs, so rather that spending hour researching, I decided ve
