Configuring OSPF for Multiple Areas and Frame Relay Nonbroadcast

For example, OSPF can be deployed in a hierarchical structure in which the network is divided intoOSPF zones called areas. In addition, OSPF operates differently on different types of interfaces.This lab focuses on a multiple-area OSPF network, with Frame Relay (that is, nonbroadcast) interfaces.Ethernet (that is, broadcast) interfaces are also addressed. An OSPF troubleshooting scenario, integrated into this lab, explores the need for virtual links onsome OSPF networks. The objectives of this lab are as follows:■ Reviewing OSPF network types■ Configuring OSPF■ Verifying OSPF neighbors and router IDs■ Describing the need for virtual links■ Configuring virtual links■ Verifying end-to-end connectivity Step 1: Configure and Verify Basic OSPF Connectivity—Initial Configurations Initial Configuration...

Final Configuration of Basic configuration CISCO Route

Giving a description of the interface is very important to help users of information relating to the interface, especially for large-scale networks is very important provision of this description. Description will also appear in the configuration file, although giving a description will not give any influence to the system. To configure an interface description, enter global config. Then go into interface config by using a command like the following description: - Use the configure terminal command to enter global config- Enter the interface to be configured, eg interface ethernet 0- Enter a description, for example, XYZ Network, Building...

Basic Configuration of Cisco Router

All CLI configuration will change the router to global configuration or global config. Config global configuration mode is most important. Global config is used in routers to execute configuration commands. The prompt shown in the global config mode: Router # configure terminalRouter (config) #  Below are a few modes that can go into global config mode:- Interface mode- Line mode- Router mode- Subinterface mode- Controller modeType exit from one of the above modes will return to global config mode. Emphasis Ctrl-Z will return to privileged EXEC mode.Configuring a router name   A router should have a unique name. Giving a name is...

The introduction of cisco IOS

Router or switch will not work without operating system. Without operating system, hardware will be useless. Cisco IOS has the ability to: - Basic routing and switching functions- Access to the secured network keamannya- Operates at the network scale CLI can be accessed in several ways. In general, the CLI is accessed through a console terminal. Console using low-speed serial connection that plugs directly from the router to the PC. CLI can also be accessed via a remote connection via dialup modem to the router AUX port. The third way is via telnet to the router. To access via telnet, at least one router interface is configured network address...

Connect Personal Computer to The Router

The first time the router is used, no network is configured, so the router can not communicate with other networks. To set up the router to connect to the network, then the necessary initialization and configuration. It is necessary to roll-over cable is connected between the management port to the computer via a terminal emulating software like hyperterminal. After configuration, the router is ready for communication with the network. Below, the steps to connect the PC to the router: 1. Configuration to a PC with terminal emulation parameters: - COM port that is used - Baud: 9600 - Data bits: 8 - No parity - Stop bits 1 - No flow control 2....

Wide Area Network (WAN)

WAN is a data communications network at a large geographic area like a province or country. WAN always uses transmission facilities provided by telecommunications companies such as telephone service company. Characteristics of WAN: - Connect the equipment is spread over a wide geographic area - Using public service channels, such as telecommunications companies to form a network in the role in the     geographic area. - Using a serial connection to access the bandwidth across the geographic area. A WAN operates at the physical layer and data link layer of the OSI layer. WAN connecting over a LAN within a broad geographic...
