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 […]
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
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
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
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
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
