The spanning-tree portfast command is a very simple feature but often mis-understood. In this short post I will explore how this feature behaves, how it works and how to configure it on a cisco switch. Portfast is a Cisco Propietary feature that was originally developed to overcome an issue when a PC was trying to […]
These pages are no longer being updated as I passed the Lab exam in August 2015, receiving my CCIE Plaque through the post was the end to a very long journey.

My all time top post was: How to build CCIE V5 Lab with CSR100V routers
Remember, the only way to achieve CCIE is "Relentless Pursuit" - Don't give up!
All the posts below are in chronological order from when I passed the CCIE Lab
EIGRP Named Mode or Multi-AF Mode is a new development in EIGRP starting in Version 15.x Its reason for being is to simplify the EIGRP configuration into one place, as previously with EIGRP classic version the configuration was between the interface and the global process which made it harder to see all the configuration relating […]
Software defined networking (SDN) is an approach to computer networking that allows network administrators to manage network services through abstraction of lower level functionality. This is done by decoupling the system that makes decisions about where traffic is sent (the control plane) from the underlying systems that forward traffic to the selected destination (the data […]
In computer network engineering, a Request for Comments (RFC) is a memorandum published by the Internet Engineering Task Force (IETF) describing methods, behaviors, research, or innovations applicable to the working of the Internet and Internet-connected systems. The list below details all RFC’s relevant to the CCIE Routing and Switching track. CCIE RFC List OSPF RFC […]
If you are looking for an MPLS Tutorial or step by step mpls configuration examples, this basic MPLS configuration example will guide you from configuring the first router to 3 router MPLS core with 2 external sites. Building the simple MPLS topology below this will consist of a 3 router MPLS core and two remote sites […]
How to build CCIE V5 Lab using ESXi and CSR1000v Cloud Services Router This post will detail how to build a CCIE v5 lab using Vmware and the Cisco CSR1000v cloud services routers. It will detail the issues I faced which should hopefully help you make this build a lot easier. The basis of this topology is […]
