I passed the JNCIA-JUNOS (JN0-101) exam today 🙂 after a couple of weeks study, so thought I’d knock up a quick blog post about the experience and how it compares to other vendor exams I’ve taken. Firstly, the main reason I went after this cert is that I worked on the deployment of a new […]
I’m currently working on an Avaya VOIP implementation, and thought I’d blog about some of the configuration steps involved along the way. First of all let’s set the scene with a massively oversimplified network diagram that shows how things hook together. We have a DHCP server and an Avaya CS1000E Communications Server, a Cisco […]
Well, that’s my first year of blogging done and dusted, so what did I achieve in 2012 and what would I like to do in 2013?  2012 was a really enjoyable year, and at the same time it was probably the most challenging of my career in Networking so far. I started the year intending to […]
Hello, is there anybody in there? Â Just nod if you can hear my EIGRP hello packets being multicast to 224.0.0.10…. Apologies to any Pink Floyd fans out there, but the opening line to Comfortably Numb describes perfectly what happens when an interface starts participating in an EIGRP routing process (well, not really). As […]
With clever, dynamic routing protocols (RIP, EIGRP, OSPF et al) being able to learn routes all by themselves, and even adapt to network problems by re-routing traffic when a link goes down, why would you even bother using boring old Static routes to get your packets to their destination? Well, in defence of Static routes […]
Before getting into the detail of the various Routing Protocols, lets go over some of the fundamental concepts and principles of IP Routing, starting with an explanation of Distance Vector routing protocols….. Distance Vector Routing Protocols examples: RIP, IGRP, EIGRP a router using a DV protocol knows 2 things: Distance to final destination Vector […]
So…..I passed my SWITCH (642-813: Implementing Cisco IP Switched Networks) exam back in March of this year, and after a lull of 5 months I’ve decided to get back on track with my certification goals. One of my goals at the start of 2012 was to achieve CCNP certification in Routing & Switching by the […]
Having recently emerged relatively unscathed from a Check Point Smart Management Server upgrade, I thought I’d blog about the experience – mainly for my own future reference, but if it helps anyone else out then that’s great too! I needed to get our SecurePlatform, Open Server based SMS from version R71.10 to R75.30, so I […]
One aspect of the Check Point SecurePlatform OS that I struggle to get my head around is backups. There are a few different options, and during the course of researching an upgrade I came across the best explanation I’ve seen yet. I’ve decided to grab a copy of the relevant text and post it in […]
This blog post details how to back up and restore Check Point Security Management Servers and Security Gateways running on the SecurePlatform OS, on Open Server hardware. There are two types of backup available – Snapshot and Backup. **note** it is recommended to only carry out backup procedures during a maintenance window due to the […]
