How To Configure OSPF Router ID on Cisco

In the previous article I’ve discuss about Router ID Concept.  And in this article I’ll discuss about how to configure OSPF Router ID on Cisco. The Following is the topology are used :   Based on the topology above, we want to configure step by step to find out the router-id changes. Configure interface G0/0

How To Configure OSPF Multiple Area on Cisco

At the previous article I’ve discuss about How to Configure OSPF Single Area. And in this tutorial I’ll discuss about how to configuration OSPF Multiple Area. The Following is the topology are used :   Once configure the OSPF Single area, we only need to advertise each router with backbone area (Area).  But when configured

How To Configuration OSPF Single Area on Cisco

In this tutorial I’ll discuss about configuration dynamic routing ospf with single area. Before we start, you can read on the previous article for OSPF area https://www.taufiknurhuda.web.id/2022/03/09/ospf-area/ The following is topology are used :   First, configuration the ip address on routers : IP Address configuration R1 : R1(config)#int g0/0 R1(config-if)#ip add 12.12.12.1 255.255.255.0 R1(config-if)#no

OSPF DR & BDR Concept

Every router that enable ospf routing protocol will try to achieve adjacency condition with neighbor routers. The following as the example topology : Imagine that all of the routers are do adjacency each others, it’s looks like that : With 6 Routers in one topology with each router send the ospf packet it will cause

Basic Configuration OSPF (Open Shortest Path First) on Cisco Router

OSPF (Open Shortest Path First) is an interior gateway protocol (IGR) for routing ip that operationg with a single routing domain  or single autonomous system. this routing protocol uses a link state routing algorithm and uses Djikstra algorithm. In this tutorial I’ll explain about basic configuration OSPF on router cisco. The following is the topology

Initial Setup Cisco WLC 3504 Cisco PaketTracer

Hello everyone. in this tutorial I’ll explain about initial setup of Cisco wireless controller with simulator cisco packet tracer. In this tutorial is aims to understand about the concept of initial setup cisco wireless controller. Here’s the topology are used : The default ip of wlc is 192.168.1.1. so you need to configure ip address

Spanning Tree (STP) Root Guard

When we implement layer 2 network, the standard STP doesn’t provide protection to change root bridge when there are one switch or connection port is down. Root bridge also can be change when bridge network received superior BPDU’s and change root bridge to undesired switch. To solved the problem we can implement a root guard.

How to remote Devices inside NATed Network

When you are as a network engineer that you will have to access your devices but you’re connection only have one public address on router and other devices are NATed inside the router. How can we access it ? In this tutorial I’ll expain how to do that. we can use static nat with custom

How To LoadSharing Dual Link Connection with PBR & IP SLA Cisco

Hello everyone, in this tutorial I’ll discuss about how to configure loadsharing connection with DualLink Internet use PBR and IP SLA on Cisco.  For the example bellow I have two Internet link for 1st link on ISP1 and 2nd link on ISP2. Then I’ll Divide the connection for the http/s, DNS through ISP1 and other

How To Configure IP SLA Cisco

Hello everyone, in this article I’ll create a Documentation of my learning about configuration IP SLA. IP SLA are used for monitoring connection and automatically failover link when we have two network link or ISP and we need to have automatic failover when primary link goes down. The Following is the topology are used :
