The second day of Network Field Day 2 started early at the Juniper EBC, luckily Abner Germanow was prepared with breakfast for the weary and slightly hung over delegates. He gave us an overview of Juniper Networks as a whole including some back history of how they started innovating by putting routing code into ASICs. He quickly handed of to Dan Backman who started off by talking about how Junos has developed itself around workflows. He demonstrated the extensibility of Junos through tools like XML and API calls. Because of the way it was developed, they have the unique ability to provide powerful scripting and automation tools. Dan actually told us that the entire Junos back end is XML, which is VERY interesting. Next he brought up a live Juniper lab to show us the real power of their scripting/automation. This is the first time I’ve heard of Junos commit scripts, which I now wish I had in IOS. During this entire demonstration all of delegates really seemed to enjoy the flexibility Dan was demonstrating, by the end, he had us all drooling over it. And that was before he dropped the bombshell… his entire demonstration had been running inside of Junosphere. Before we were able to bombard him with questions about how to get access to it, he showed some a rather impressive demo using Cariden Mate, and an IS-IS db gathered from what appears to be the I2 backbone. Very cool stuff. Cariden was able to generate a topology from the database, and their plugin for Cariden was able to generate the appropriate Junosphere configuration/startup files. Several times during his presentation he made reference to there being “one more thing” or some secret he wanted to share. It wasn’t long before we learned they were going to give us access to Junosphere for testing! Be on the lookout for my Junosphere review once I’m able to check it out.

My most recently collection of interesting bits of data found out on the blogsphere/internets. Due to my lack of time, I’ve decided to recycle what I find out on the ‘net and share it here. Please bare with me while I try to come up with an interesting name for such an unoriginal type of post.
Juniper/Junos Portable Library
Greg Ferro ala Etherealmind.com posted an interesting link. Instead of hiding their documentation behind a pay-wall, Juniper has supplied all of it via a mutli-part zip files. As Greg mentioned, loading these on your iPad is a great option for the engineer on the go! [link]
Cisco’s failure to provide IPv6 – Updated!
Ivan Pepelnjak from ioshints.info has some pleasant surprises for us in the Cisco-land with an update on Cisco’s IPv6 support in their data center products. [link]
Nexus 1000v features
Yandy Ramirez aka Packet Maniac has put together a great Mindmap detailing the features of the Nexus 1000v. [link]
IOU – IOS on Unix
More news from Jeremy Gaddis ala Evilrouters.net. He has not only documented the use of, but improved the functionality of the iou2net.pl perl script that replaces the functionality of the hard to come by IOUlive. [link]
Cisco Phone Cheat Codes?
Yes, you had to read that title twice. Tom Hollingsworth aka Networkingnerd.net has put together a cheat sheet for those of us that tend to forget the keypad shortcuts for Cisco’s phone line. [link]

As a follow up to my JunOS Olive tutorial, I made a demonstration video that shows Multicast functioning via OSPF to another Olive and an ImageStream VM.

Interested in trying out JunOS? Can’t afford to build a real Juniper lab? Sounds like you need some Olives. No, we’re not talking about the green fruit commonly seen in a martini glasses across the nation. Olive is the codename name given to JunOS software running on something other than a Juniper router. It can either run on a PC of similar specifications to a Routing Engine, with no forwarding hardware (or PFE) attached, or inside a Virtual Machine (VM). If you took a Routing Engine out of a Juniper router and booted it in a blade server chassis, it would effectively be an Olive.
This guide is to help you run Olive inside vmware to create a virtual Juniper router lab. You can also extend your lab to dynamips (Cisco Emulation), or other router VMs that you may have. My screenshots will be from VMWare Fusion on Mac OS X, but should work perfectly well, possibly even better (since you’ll be able to setup multiple interfaces) on VMWare Server. At some point, I would like to test using VMWare ESXi as well.
