This article is all about Router security.Here in this lab we will discuss about console password,auxiliary password,enable password,enable secret password,telnet password with telnet configuration,username with clear text password,username with encrypted password,service password-encryption on router.

So to demonstrate all above security on router I am going to use cisco packet Tracer software.This is one of important portion for ccna certification students and also important with networking  point of view because it is directly related with router security and as we all know Routers are the backbone of every IT company. (more…)


This is a basic ospf configuration lab using two routers. Using two routers ospf configuration have been done in this lab. I have used cisco Packet tracer software to demonstrate the ospf configuration. This if you are learning or preparing for ccna certification or ccna training then this lab is for you. Simple and to the point in just few simple steps.

I hope you can clearly see the OSPF Topology diagram drawn below. And now if you can see you can clearly analyse that there are total three routers in this topology table and total three networks.
