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
Configuration Radius Server Userman Mikrotik RouterOS v7
Hello Everyone, in this tutorial I’ll discuss about configuration radius server on mikrotik routeros version 7. On the routeros v7, you can access userman configuration in winbox so it’s doesn’t need to configure on web based. Here’s the topology are used on this tutorial : First configuration the ip address on router core and
OSPF (Open Shortest Path First) Concept
On This Article I’ll discuss about concept or how to ospf work. When we enable the OSPF on routers, then the router will be achieve adjacency condition with neighbor router. The Adjacency condition is a condition where between two routers neigbor already connected and agreed to run ospf routing protocol. If these condition are not
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
