This tutorial is all about how to configure RADIUS SERVER so that our  cisco router telnet get its access from RADIUS SERVER Configured.If you configure telnet on router it takes password which was assigned to it during telnet configuration,but after configuring RADIUS SERVER telnet will get it’s authentication from RADIUS SERVER.So after its configuration you will see that you will not be able to remote login to router R1 using telnet password,but you can remotely login to router R1 using telnet if you use the password mentioned in RADIUS SERVER.

Here in this Lab i have shown how to configure a single Router to work as four DHCP SERVER.To show configuration i have used cisco packet tracer software here.This lab contains 1 Router, 4 switches and 8 computers.All four switches in this Lab are in different network and the computers in each network get their ip address through router using DHCP.Since ther are four network here,therefore we need create four different DHCP POOL on router to provide ip address to machines or computers located in four different networks.

This is a static routing lab in which we will learn how to configure static routing for a network having three routers inside packet tracer.Here in Lab there are four network 1.0.0.0/8, 2.0.0.0/8,3.0.0.0/8 and 4.0.0.0/8 and three routers.

To make PC0 communicate with PC1 we must configure route,because they are in different network and is connected via routers. (more…)

This tutorial is all about how to configure software raid-0  in RedHat Enterprise Linux.Even if you are new to Linux you can easily configure RAID-0 by reading this article.I have written raid-0 creation notes step wise from begining to end.In this article instead of two hard drive i have used two different partitions to show you how to create and configure software RAID-0 in Linux.RAID-0 is also known as No RAID because it doesn’t provides redundancy.To create RAID-0 array minimum device/partitions required is two.RAID-0 write data on different hard drives and hence increase the read-write speed.RAID-0 is needed only where we needs performance but no redundancy.

We already have learned how to configure static route and Dynamic Route(RIPv1,RIPv2,EIGRP,OSPF) on Cisco Routers.Today here we learn how to configure Default Route on Cisco Router.Before configuring default routes you must know why we need to configure it and where we use it.The reason behind configuring default routes is that it has capacity to direct packets destined to networks not found in the routing table.Default Routes are configured mainly in STUB NETWORK.
STUB NETWORK:A network having only one exit interface or only one route to reach the destination.
When we configure default routes,it directs these packets to another router that has the route to destination. (more…)
