Compilation of Study Notes

As per the previous blogs if you have followed from the start you will notice you have downloaded, installed, and configured your Juniper SRX to support IDP technologies. This is a great start. For most users the default templates defined…

Working on my CCIE written, I have been labbing many things. One thing is constant and that is many tabs and lots of configuration. When initially configuring devices and confirm bulk checks across the many devices you don’t want to…

As I march onwards to the CCIE written the need is apparent that you must understand every trick and caveat of a routing protocol. I have been reading up and working on RIP this weekend and amongst the funny situations…

I have a various number of devices in my lab. I constantly deploy them, rework them, and lab new things. Once up and operating I generally move off a console connection and move to SSH. Well sometimes there poses a…

Quick one today and a memory refresh for myself. Routed L3 links between a SRX and an EX2200-C. I have currently two up links connected between the two. I want to advertise a L3 VLAN across to the SRX. I…

The Nexus series of data center switches by Cisco allow for an extended fabric configuration. By utilising the notion of remote line cards, an engineer can deploy Nexus 2200 series switches as Top of Rack. These top of rack switches…

As many of you are well aware I own a Juniper Networks SRX110H-VA firewall. THis firewall has been the focus of many blogs up until now. I have covered off a myriad of subjects with many more to come in…

Back on the juniper posts today, I am going to jump into local user authentication. Juniper offer quite a few options on configuring user based access. I will start to explore these among many other topics this year. I am of the…

Certification testing happens all the time in our industry. Certifications come and go and technology changes. There are two things that remain constant. The pursuit of knowledge and higher learning, and passing/not passing. The pursuit of knowledge is what differentiates…

Just a quick one today. I had planned to take the JNCIS-Security this month but accidentally booked JNCIS-Enterprise. Not to worry in the slightest. The same great content will be served up, just with a focus on routing and switching.…

Now some might say this is a silly blog post, especially since I have an Opengear 5004 console server. At this stage I haven’t explored all its uses so it is not in “production” at home. I currently SSH home…

Wow, not a Juniper post. I bet those of you who don’t use Juniper are excited? Today is a handy blog for your toolbox. I work on older hardware now that I am an ex-gamer and dedicating my time to…

Next topic on the blog is Security policies. An important part of firewalls is controlling of traffic. Once we logically define zones and we segregate the network we need to control traffic to and from these zones. It is important…

Juniper works very different to IOS. If you have been following my blog recently you will have discovered I have been on the Sauce. Fresh of the JNCIA Junos pass I am diving into JNCIS-SEC. I am going to explain…

Like Cisco, Juniper offer their equivalent to security levels. Known as zones, the SRX family can classify common interfaces and apply hierarchical policies that allow stable scalability. This post is designed to introduce Cisco people to the Juniper equivalent, and new…

As I slowly diversify my skill set and acquire JUNOS knowledge I find that knowing the technology and underlying concepts are the same. Minor changes like routing preference and the like is easy to deal with. Slowly I am working…
