Welcome to a new series of blog posts that I am working on. It is the intention of these interviews to bring a human side to the technical author. I feel that each author has a story to share , and I wanted to provide them a way to share that story.

Our first author for this series is Peter V Southwick whose latest book is Juniper Networks Warrior published by O’Reilly Press.

Junos – IS-IS

Jeff Fry published on 2013-02-11 included in How To Junos

Here is our IS-IS Lab Topology ISIS Lab Topology

Time to do some IS-IS labs. I am going to try and make these short and simple. I am sure as I get more into Junos I will write more complex IS-IS topologies and start to include LDP as well.

Junos – OSPF and Rollback

Jeff Fry published on 2013-02-07 included in How To Junos

Ok, time for some OSPF and I will also cover Rollback (Love this feature) Here is our OSPF Topology, we will only do Single Area for this lab. OSPF Lab Topology

Ok, time to rollback to the rescue configs.

Up first replacing the config on R4 (if you have not done this in the last lab)

Junos – RIP Authentication and Preferences

Jeff Fry published on 2013-02-04 included in How To Junos

Ok, time for our next Junos topic – RIP Authentication and Preferences. Below is our lab topology. RIP Lab Topology

Let’s do RIP Authentication first.

First, up – md5 authentication between R4 and J1 only.

For this exercise, we will use the password of JNPRCSCO for the link authentication between the routers.

Here is a quick reminder on what the lab looks like:

RIP Lab Topology

Ok, time to get some routing. First up, Routing Information Protocol, RIP!

So, first up we will configure the Cisco router, R4 for RIP.

Cisco Live US – Keynote Information

Jeff Fry published on 2013-01-26 included in Cisco Live

Well it seems that once the tap has been opened, information starts to flow! Recently Tom (@networkingnerd) and I posted some information around Journey being the band at the Customer Appreciation Event, that is again being held at Universal Studios. Well, we have just gotten some more news around the keynotes and schedules and I wanted to make sure I shared what I have with you as soon as I could. Journey

So, here is what we know…

Your host with the most…

It would not be Cisco Live without our wonderful host, Carlos Dominguez! I believe that this year will mark his 5^th year for hosting this event. And to be honest, I cannot remember who hosted it before, he just does it so well and naturally! Glad to have you back, Carlos!

Starting the Universal posts and Journey to Cisco Live US – Orlando

Jeff Fry published on 2013-01-24 included in Cisco Live

Well, it is getting to be that time of year when we start talking and getting ready for Cisco Live. When I say WE – I am referring to Tom (@networkingnerd) and John (@mrtugs) as we have done this for the past few years.
I just wanted to get this information out to you, so my Why you should go and the Venue information posting will come soon.
So, let us get to the part that everyone wants to know, where is the CAE and who is the band? Well, if you looked at the title of this post you might have figured it out.
First up – the band we chose in the voting poll is…..

Junos – J-Web

Ok, time to get back into the Junos swing of things. Up next is J-Web.

Here is a quick reminder of the topology that we are using for these labs.

Hardware Topology

Junos devices have a web interface called Jweb. I am not going to cover using JWeb, but I will show you how to enable it and access it.

For this lab I have enabled connectivity to J1 from my home network.

To enable J-Web on the device, issue the following command and commit it.

[edit]

jfry@J1# set system services web-management http

[edit]

jfry@J1# commit and-quit

commit complete

Exiting configuration mode

Ok, time to see what this looks like. From a web browser, enter the IP address of the router http://192.168.14.1

Missing in Posting

Jeff Fry published on 2013-01-17 included in

Ok, I will admit I have been missing in action for too long. Was starting to think of putting my face on that carton, but I will spare you that imagery. The holidays are a busy time for me with family and such, so that is part of it. The other part of it is that I left my employer, NTT, in December after a year of being there. It was my decision to leave, and I did it based on some internal factors that I would rather not mention. I enjoyed working there and with the team that I was on. There are some good people on that team that have a bright future! So, where did I end up? I took a position with Torrey Point – http://www.torreypoint.com/ – as a Network Engineer focusing in Post Sale deployments. Something that I feel I am well suited for, as well as looking forward to the challenges that will be presented. I have been with them since I left NTT in December, but have not had a chance to post anything here. One really great thing with Torrey Point, I will get more hands on time with some Juniper equipment! Love building my skills – and this is the perfect opportunity for me to do that. Now that that is out of the way, look forward to some more Junos workbook posts in the coming week. I did complete my JNCIA in December ’12 as well, and based on some of that study – I have made a few quick edits to the Junos workbook, and more around the J-Web interface post that I am working on. Thank you and good luck in 2013! Oh yea – See you at Cisco Live Orlando in June!!!

Junos – Interface Configuration and Connectivity

Jeff Fry published on 2012-11-13 included in How To Junos

Now it is time to get some housekeeping done on these routers. We will configure the interfaces on each of them. Once that is complete, we will create a Rescue configuration. A rescue configuration is a known working configuration that we can roll back to at any time. We will use this rescue config to reset the routers to a base state before each lab. Here is our Lab Topology:

First up though, we need to get R4 (The Cisco router) configured and setup.
For R4 we need to configure E0 with an IP of 192.168.14.4/24 and the loopback with 4..4.4.4/32. Once we have it configured, we will save the config to FLASH as base.txt so we can reload it later on.
Router#
Router#conf t
Router (config)#interface Loopback0
Router (config-if)# ip address 4.4.4.4 255.255.255.255
Router (config-if)#exit
Router (config)#interface Ethernet0
Router (config-if)# ip address 192.168.14.4 255.255.255.0
Router (config-if)#no shut
Router(config-if)#exit
Router(config)#hostname R4
R4(config)#exit
R4#wr mem
