In a branch office you generally have workers who work standard business hours. These generally exist between the hours of 0700 and 1800 hours. Most branches have VOIP handsets or APs that run off PoE. These do not need to…

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 buzzword in the industry of late is DevOps. It is one that I hope isn’t tarnished by the marketing machine where buzzwords go to die. DevOps is the shift in the paradigm of network and infrastructure management. Centralized infrastructure…

My Juniper lab is at home and contains an EX2220-C and a SRX110. Traditionally I created an interface in which I could SSH to. This worked for a while but when labbing you are generally testing new things. Well needless…

Today was a good day. I had a new arrival into the family. The Juniper Networks EX-2200 12-C PoE+. In addition to my SRX110-H-VA Firewall I now have a fully fledged JUNOS switch with all the bells a whistles. Juniper…

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.…

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…

Today I passed the Juniper Networks JNCIA JUNOS exam. I am quite elated to be honest. My roots as a network engineer have come from the Cisco Network academy and I have climbed part of their certification tree. Upon acquisition…
