CCIE Quest

This tutorial will demonstrate process of setting up a Session Initiatition Protocol (SIP) trunk on Cisco Unified Express Communication Manager Express (CUCME) to SIP Voice Over IP (VOIP) Service Provider. It will be divided into several parts. This is first part in which you will learn to setup Basic SIP trunking with VOIP service provider. This will be followed by a more Advanced  configuration tutorial which will (more…)

This tutorial will walk you through the process of settting up a distributed GNS3 topology where you can use different external hypervisor engines and run GNS3 topology in much easier and smoother fashion.This helps you utilize resources at hand in an efficient manner by distributing processor load across multiple hardware platforms. Most people use WindowsXP / Windows Vista on their laptop machines. However, for GNS3 and dynagen to perform at their peak, i would recommmend you to use a flavour of Linux which speeds up things to greater extent.

I will be using (more…)

In this tutorial, i will demonstrate configuration of IPv6 addressing in both Windows XP machine and Cisco Router (GNS3).One of most flexible migration approach to IPv6 will be  “Dual-stack” approach which means that network devices will have both IPv4 and IPv6 addresses simultaneosly. Both TCP/IPv4 and TCP/IPv6 protocol stacks will work together seamlessly for quite some time.

IPv6 is also called IPng “IP Next Generation”. IPv6 offers exciting (more…)

This tutorial will help you lock down your Cisco gear’s configuration access.This feature comes in very handy for making day-to-day configuration changes.The “Configuration Lock” feature also known as “Exclusive Configuration Change Access ” allows you to have exclusive change access to the Cisco IOS running configuration, preventing multiple users from making concurrent configuration changes to Cisco devices.

In addition, this tutorial will also demonstrate use of (more…)

Recently, i came across a post at CiscoBlog for scheduling periodic config backups in IOS to an external location on your network.This is useful  if you want your router to trigger an update everytime ‘write mem’ is executed.However, in some cases, this might not be desirable considering the amount of log files and number of devices on your network.

I usually prefer taking back-ups at mid-night on daily basis.In order to achieve this task, i would use ‘archive command’ in conjunction with (more…)
