Cisco is the major OEM in IT sector. In this categories, we will focus on configuring Cisco routers, switches, firewalls, wireless devices etc.
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 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, …
OSPF (Open shortest path first) is one of the most popular routing protocol used in enterprise networks and ISPs, because, it’s very efficient and scalable. It’s also an open standard routing protocol, meaning, any OEM (like Cisco, Juniper, Brocade, etc.) can implement this. Today, we will discuss, how to configure OSPF in Cisco routers. To …
