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.

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.

Today I am here to discuss ssh configuration and ssh configuration options on routers in little more detail. using cisco packet tracer software here i will show you not only how to configure ssh over cisco router but also show you how to configure other ssh setting on router properly.Before we go ahead in this article i will love to brief you guys about the steps i will follow to do this lab.

Even you have Basic Knowledge of networking you can easily understand this lab and can configure ssh on any router with all other settings.

 

1.Configure Router Interface ,assign ip address and gateway ip on PC and Then Verify Communication using PING Command.

2. Configure hostname and domain name for router

3 Configure RSA key

4.Enable SSH v2

5.Configure other settings for SSH

6.Create user account for ssh and password with higher priviledge.

7.Configure VTY Line for SSH

7.Check ssh connection from remote pc.

8.Check ssh version and other settings

9.Check or see public key you created

Today through this article i will try to show you how to configure load balancing or load sharing using static routing.I mean one can use static routing too for load-balancing.Here in this architecture we have total 3 routers R1 ,R1 and R3. When any traffic generated from R1 for R3 it can travel in two ways: In other ways you can simply say that when we want to send something from PC0 (1.0.0.2) to PC1 (5.0.0.2) our packets reach there in two ways. here in this lab there are two possible paths to travell from pc0 to pc1. The First one is R1R3 and the second one is R1R2R3.I am going to perform this lab with the help of cisco packet tracer here.So just start learning load balancing and load sharing using static route with the help of an example lab using cisco packet tracer.

so when we have two simultaneously path to send packets from source to destination that is known as load balancing.

This article is all about redistribution configuration lab between two eigrp autonomous system . Here in this lab we will configure  EIGRP  having different autonomous number. To show Multiple EIGRP AS configuration on same router i am using cisco packet tracer. You can see EIGRP neighbors with different AS numbers in this lab and you will learn how to configure it to communicate them.In below topology diagram you can see EIGRP Topology having different Autonomous Value. There are total three routers R1, R2 and R3 R1 is in As 1 while R3 in AS 2. But R2 is in both AS.Now read carefully how i am going to configure it.
