In this lesson, we will learn how to configure SSH on Cisco IOS enabled devices. This tutorial will show you how to enable SSH, generating RSA key, and then allowing on SSH remote management protocol under the VTY interfaces. This will also show you how to add more security in SSH access and some best …

In this lesson, we will configure iBGP on Cisco Router. This is the second part of our BGP series. We have chosen a network where we have three routers which are not directly connected. We will configure ibgp among them and check the reachability from end to end. Below are the list of our BGP …
BGP is an exterior gateway protocol that manages how packets are routed across the internet. It can quickly adapt to send out packets if a path goes down. Because of the variety of ways to do the traffic engineering, this is one of the most popular routing protocols. A series of articles will be published …
When we have VLANs in our network, two separate VLANs can’t communicate between them, unless we do the routing between them. Which means, we need a router (L3 device) to make communication between them. In this lesson, we will configure router for inter VLAN routing. To do that, we will follow below topology and our …
HSRP (Hot Standby Router Protocol) is one of the most popular First Hop Redundancy Protocols (FHRP) made by Cisco. It is Cisco proprietary protocol. The FHRP allows a router on a LAN segment to automatically take over if other fails. Today, in this lesson, we will learn to configure HSRP on Cisco IOS. We will …

A VLAN (virtual LAN) is a logical sub-networks of workstation. This is needed for network admin to partition a single switch network into many. It improves security and traffic management. In this lesson we will learn how to configure VLAN on Cisco Catalyst switches. We will start with a simple network where we need to …

A variety of risks exist when deploying a routing protocol in a network. It’s very much true for OSPF. It’s because, OSPF does not have any built in authentication mechanism for peers. You need to configure OSPF Authentication, to make your neighbor establishment secure. Today we will configure OSPF authentication for our demo network. So, …
