OSPF Cost Manipulation on Cisco

On the previous article I’ve discuss about OSPF Cost Concept. and in this article I’ve discuss about OSPF Cost Manipulation config on Cisco. Here’s the topology : First, make sure the ospf already running on your lab. in this article I’m use the EVE-NG and all of routers use 10Mb/s interface speed. Configure IP Address on

How To Configure SNMPv3 on Cisco Router/Switch

In this tutorial I’ll discuss about how to configuation snmpv3 on cisco router or switch. The different snmpv3 with snmpv1 or 2 is more secure connection for snmpv3.  SNMPv3 provide the authentication and encryption method for the connection between NMS and managed devices. We also use the paesless testing tool for the test snmp v3

Configuration and Manipulation OSPF DR & BDR on Cisco

After In Previous article we have discuss about OSPF DR & BDR Concept, Now I’ll discuss about configuration OSPF DR and BDR on Cisco. The Following  is topology : We have four routers which running OSPF routing protocol and where the routers have different resources.  R1 has high resources, R2 with middle resources, R3 &

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 Cost (Route Metric)

When we use a Dynamic routing protocol, there is one condition where more than one path to reach a network. So router will select the best path toward one network from the some available route path. To specify a bestpath from a few route path is use a paramenter called as metric and OSPF use Cost as

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

OSPF Router ID Concept

Every Router that running OSPF in a network it must have an unique identity called RouterID. This ID is used 32 bit format number like an ip address format. This number are used to identified on one router with other routers. Router ID also used by OSPF to DR and BDR selection process. To Specify

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
