- IPv4 and IPv6 Global Multicast Addressing (10/15/2013) - Global Multicast Addressing: IPv4 and IPv6 This is a short post covering globally unique multicast IP addresses for both IPv4 and IPv6; this does not cover IGMP, MLD, PIM, BGP-MP, MSDP or any other MC technology other than global addressing. Whole books are dedicated to multicast so I’ll try and keep this focussed! Multicast […]
- What are VRFs? (9/22/2013) - VRFs provide extremely useful functionality which are not just limited to MPLS type solutions. Read this article if you need the basics clearing up!
- Junos Stretch VLAN Using SRX Branch – who needs Cisco’s OTV? (6/18/2013) - Traditional and modern Enterprises often suffer from inflexible service providers either charging over the odds, taking forever to make changes, or providing overly complex and unreliable services. SDN is beginning to threaten the way things are done in the data centre and enterprise, moving all the complexity up to a different level. The dawn of […]
- Cloud Fog – Automation and Ruby step 1 with Junos (5/21/2013) - Day 1 of network automation using Junos and Ruby. Networks are not only cloudy, but foggy!
- F-VRF IPsec (10/3/2012) - Front door IPSec VRF’s (Virtual Routing and Forwarding instances) are massively useful concepts within network operating systems. In the service provider industry VRFs are very much bread and butter. In the enterprise arena, they may also provide useful functions, although it is not as common to see them. Cisco with the Nexus 7k range have […]
- Networking Consultants (10/3/2012) - Business acumen in networking There are many arguments which may define how successful a project or rollout will be. Some claim success is down to the sales force, engineers will argue it’s down to pre-sales coupled with technical skill and project managers will claim they’re the pivotal element. Fact is, it’s a well oiled combination […]
- Skilled teams and the not so skilled… (9/25/2012) - It would be so nice for everyone you work with to be reading from the same piece of paper, including management and the people who hold the purse strings. The Dunning Kruger symptoms are discovered far too frequently, but like any American conspiracy movie (Shooter?), work is a huge game of politics, glory hunting and […]
- Cisco ME3750 – EoMPLS over ES ports (9/20/2012) - Bread and butter EoMPLS The Cisco ME3750 is an Ethernet services switch compliant to MEF 9 and 14. It can serve in a multitude of roles from delivering Martini draft L2 connectivity, providing H-QOS, VLAN re-writes, QinQ, CFM (OAM)…the list goes on. It will also provide L3 MPLS IP-VPN functionality, limited by throughput (due to […]
- Router to a brick upgrade (8/29/2012) - Routers in this day and age scale from small processor and single chip solutions, through matrix multi-chassis driven systems like the Juniper TX Matrix formed from their T4000 and T1600 devices. Software tends to be broken, sometimes catastrophically, other times mildly, and the engineering fraternity in general accept it. Salesmen generally believe that Cisco devices […]
- Journey of PRIDE (8/21/2012) - Working in network communications takes a certain mind set, with an innate ability to laugh off issues whilst simultaneously peddling frantically below the surface to prevent sinking. You are ultimately an engineer, a project manager, a commercial delegate, a ‘blame mule’ and the saviour when all hell breaks loose. In short, I love it, but it […]
- Be TACtful with Cisco (8/20/2012) - Anyone who’s worked in networking long enough will have at some point dealt with the Cisco TAC (prepend dreaded for more of an effect). I remember clearly an issue back in 2009, in which the company I was working for at the time had a pair of 6513s with Sup7203Bs and first generation 10GE cards […]
- Film Technology (8/20/2012) - Film Technology = >_< So, you’re out at the cinema with your loved one, munching on popcorn (literally eating money) and you’re ready for the film. You’ve found your comfy spot in the chair for the next few hours and the got your hand firmly clasped on your Coca Cola bucket. Iron Man! W00t! […]
- I <3 Junos! (6/11/2012) - For years I’ve been one of those engineers who tends to loiter in the background. A lot of forums I’ve read tend to focus on basics, whilst others tend to leap off and explain vast subject areas in less than a couple of paragraphs (getting quite a few details incorrect whilst they do it). I’ve […]
