What do you know about IPv4? Having a 32 bit address Format (ddd.ddd.ddd.ddd) Divided into classes A, B, C, D, E IP Reserved # 10.0.0.0 - 10,255,255,255 - reserved for local intranet networks # 127.0.0.0 - 127 255 255 255 - reserved for local loop on each computer # 172.16.0.0 - 172.31.255.255 - reserved for local intranet networks # 192.168.0.0 - 192 168 255 255 - reserved for local intranet networks # 224.0.0.0 - 239 255 255 255 - used for multicast routingAn easy way to do subnetting are:Subnetting is used to subdivide the IP group into smaller groups so as to facilitate the...

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

Configuring EIGRP
The objectives of the lab are as follows:■ Configuring basic EIGRP■ Disabling autosummarization■ Load-balancing across unequal paths■ Configuring a default route■ Verifying EIGRP 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...
