A hub or switch is required for two or more computers to communicate. More than one computer connected to the Switch can communicate on the local network. As an example of a small office, an average of 4-5 computers, 2 printers are used in a switch on such a local network. An ADSL modem is required for Internet access.

But for most workplaces, such equipment will be inadequate. Big companies and companies have their own servers. And also, because the network systems of these companies with 1500-2000 employees are highly developed, the network speed should be ideal to work. When in the branches connected to the center have network troubles, it means that things can not walk in time.

Today, there are integrated routers. These devices are often referred to as wireless modems. As technology advances, very powerful Wireless Router devices are produced. However, such a business network system can not be managed by a single integrated router.

In a large firm, the integrated router can be very heavy. But you can not get out from under your work.

Can not the integrated router be used in such a network? Of course, it is used and using.

In other words, we introduced the router with a short description. They are devices that allow networks to communicate with different IP blocks. For those who do not know about the different Ip blocks, for example, a network system that exists in your home, ie the network infrastructure, must have an Ip block. Because the IP is the language of Internet. This Ip block; 192.168.1.0/24 or 192.168.2.0/24.

There is such an Ip block in the modem interface that your Internet Service Provider has provided. In general, these values are 1.0 or 2.0. A single Ip block is sufficient for home users. Up to a maximum of 254 devices can be supported by handling a class C Ip address block in a single Ip block. We can increase this number by editing the subnet mask…

You can browse the topic called “What is GNS3? and What Does GNS3 Do?” to make more detailed experiments on router devices or switches and to better understand how they work.

In summary, a company with 400 employees must use a Router. Because we can assign the remaining number of computers if it is 254 from 192.168.1.0/24 network and 192.168.2.0/24 network. We can communicate these two different networks by adding a Router in terms of network speed.

Of course, we can do this by adding the subnet mask by adding the router to the communication or by adding VLANs from the integrated router interface. But as we said, these things are for more advanced users. I wanted to explain basically what it is.

How to Use Cisco Routers and Switches?

Routers 192.168.1.0/24 and 192.168.2.0/24 can easily communicate with a network with two different Ip blocks.

How is it?

Most large enterprises use Cisco branded routers. Cisco routers have interfaces called interfaces. These interfaces are called FastEthernet or GigabitEthernet.

Based on the example we gave above, if we consider that we connect the 192.168.1.0/24 network to the FastEthernet0/0 interface of the Cisco Router and the 192.168.2.0/24 network to the FastEthernet0/1 interface of the Cisco Router, the Static Routing process We can provide the network to communicate.

The basic rationale for the routers of any Cisco router or any brand is to deliver the package from the source to the destination. Routers do this by Router. It keeps the networks with different Ip address blocks in the memory thanks to the routing table, and when a client 1 wants to reach the client 2 on another network, the client 1 contacts with the Router to reach the client 2 and says “Get me to the client 2”. And then, the communicate is completed.

The router is work like this and used. These types of experiments can be done with the Cisco Packet Tracer program and work on Cisco Exams. Or you can apply it only after you have decided to prioritize the design of your own network.

To become familiar with the Cisco Packet Tracer program, you can read the topic called the “What is CiscoPacketTracer Software?“.
