Multi-area Open Shortest Path First Lab In this lesson, we will do a multi-area OSPF Lab. To perform this lab I used Cisco packet tracer, 8 routers and 2 switches.Before making multi-area OSPF network design, 3 things always keep in mind. Area 0 (backbone area) is must, other areas can’t communicate without area 0. All … Read more
In this post, we will learn how a packet flows during ping process when destination is on different network. In computer networking, ping command is used to check connectivity. Ping works on ICMP protocol. There are two ping messages- ICMP echo reply ICMP echo request Packet flow Network topology: two different networks are connected. To … Read more
Single Area OSPF Lab Open Shortest Path First In this lesson we will perform a single area OSPF lab. Before starting lab, first we discuss a quick review of OSPF. It is a dynamic routing protocol and used inside a LAN network (single autonomous system) that’s why it is also called IGP (interior gateway protocol). … Read more
What is RIP? RIP stands for routing information protocol. It is a type of dynamic protocol, comes under IGP(interior gateway protocol). RIP works on distance vector algorithm. Use hop count as a metric (one router = 1 hop) irrespective of bandwidth. Maximum hop count is 15. It means if a route has more than 15 … Read more
Connect Two Different Networks- LAN1 & LAN2 In this lab, we will connect two different networks. We have two networks LAN1 and LAN2. So, this lab is going to be very simple. We use a router, as all we know router is used to connect different networks. After making topology and all connections, to verify … Read more
What is a Router? Router is a network hardware device that is used to connect two different networks. It works on layer 3 (network layer). The primary function of a router is- to forward the packets from one network to another by choosing a best path. Routers manage routing table that contains a list of … Read more
DHCP & DHCP LAB What is DHCP server? DHCP stands for dynamic host configuration protocol. DHCP server automatically assigns IP address to the hosts. You can configure DHCP server in a router and in a server. Why we use DHCP server? In smaller networks, we can configure IP address manually for individual host. But in … Read more
How To Configure Static Routing? In this lab, we will learn how to configure static routing. To do this lab you need to perform 4 steps- Design the topology. Assign the IP Address Configure Static Routing Verify the connectivity. Step 1: Design the topology To perform this lab, I used the packet tracer, it is free … Read more
Different types of memory in cisco device (Router and switches) In this lesson we will learn different types of memory found in Cisco switches and routers. Everyone familiar with the term memory, in simple words memory is a space that is used to store data. For easy processing and effective handling of data, memory is … Read more
Command Line Interface In this lesson, we will learn different ways to access CLI and how to use CLI to configure commands. First we will understand what is CLI? CLI is a command line interface that network engineers use to configure a device. CLI is also known as user interface because to control device hardware … Read more
