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
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 :
Spanning Tree Protocol (Root, Designated, Alternate Port)
Hello everyone, in previous article I have discuss about Spanning Tree Root Bridge. And in this article I’ll continue to discuss about Spanning Tree Protocol for Root Port, Designated port and Alternate port. Root Port After the root bridge has been determined, the STA algoritm is used to select the root port. Every non root
Spanning Tree Protocol – Root Bridge
Hello Everyone, in this article we’ll discuss about root bridge on spanning tree protocol. Root bridge are used for reference point for all path calculations on STP. So All of switch that connected are select layer 2 connection to the root bridge. Switch exchange BPDUs to build loop-free topology is beginning with selecting a Root
Spanning Tree Protocol (STP) Concept
Hello Everyone, in this article I’ll discuss about STP. What is STP ? Spanning Tree Protocol is a Loop-prevention network protocol that allows for redudancy while create a loop-free Layer 2 topology. STP logically block the physical loops in the layer network to preventing frame from cirling the network forvefer. Impact from loops it will
