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
DTP (Dynamic Trunking Protocol) | DTP Overview
DTP (Dynamic Trunking Protocol) is a Cisco Proprietary Protocol. DTP allows to switch devices select switchport mode (access or trunk) when connected to other switch. DTP has some characteristic as the following : is ON by default on Catalyst 2960 and 2950 switch series. For dynamic-auto is on by default on catalyst 2960 and 2950.
What is VLAN ? VLAN Overview
Hello Everyone, In this article I’ll discuss about VLAN. What is Vlans ? Vlan are Virtual Local Area Network.It is logical connections with other similar devices. When we placing device into vlan network, they are have the following characterictics : It provides segmentation of the various groups of devices on the same switch. It provides
Configuration VLAN Voice and VLAN Data on Cisco
Hello everyone, in previous tutorial i have discuss about configuration voip on cisco packet tracer. and in this tutorial I would like to discuss about configuration vlan voice and vlan data. Vlan voice are used for voip traffic while vlan data are used for general traffic. This is the topology are used : For voip
