The Basic Infrastructure Routing
The basic infrastructure n routing refers to the channel in which internet connection is linked and flow. The center of any basic routing is a server computer. The moment the router is connected in an appropriate manner, creation of a basic infrastructure is a very simple thing. Creation of Infrastructure Mode Access Points in a company’s communication system is similar to creating it on a single computer. When using; OS X, Linux, Mac, and Windows is an easy task. In most cases, for most Windows, the operating systems they use creates an ad-hoc network by the means that are default. For instance, one can create an ad-hoc network the system’s Control Panel in the computer Windows or create a network ad-hoc on the Ubuntu Linux machine. It is better if an individual intends to connect two laptop computers. In this case, the connection involves more than one computer for it is a company networking system.
In a company, there is a need to use Windows 7 of Windows 8 Operating Systems. It is because they facilitate easy connection to the wireless internet as the laptops with Windows can easily set an infrastructure mode that have wireless points of access. In this case, the use of a few Command Prompt commands one can therefore, easily use wireless connections available for internet access. The company networking system will function well with the Windows connection as they facilitate efficient network connection through wireless concept. The figure below shows a Command Prompt for a server/Administrator system in a wireless connection.
1. Connectivity tests for routing
The time the router is connected, there is no actual way of telling if it works or not just by looking at it. As such, an appropriate test has to be undertaken. A computer system should be brought into the region where it can access the wireless infrastructure for the internet. After that, the Control Panel is accessed and then the network and internet option is selected. The icon will open up revealing a multiple options to select from them. The two primary network and internet options that pop up on selecting are; the view network status and tasks option and the choose home group and sharing option. The first option is selected thus opening a wide page with network and internet options. You then select the option for “connect to a network.” The option opens up to a number of network options that are available. In this given case, the name of the router will pop up if at all the router is connected. If not, the name will not appear. After opening, the router option, click on the open command for connection. A router that is effective will connect without undertaking any option. Further test can be done to confirm the speed of the router after connection.
2. Basic configuration routing
Basic router configuration is a requirement in order to connect the computers of a company to the same router. Router configuration has many different configuration whereby each plays a critical role in enhancing the network performance and well-being of the router. The key basic router configurations are;
a. The default configuration:
When the Cisco router, for instance, is to boot after installation during the first boot, one will notice that basic configuration already under performance. In this given case, the user is advised to use the show running-Config command in order to view the initial configurations. The command that will be in provision in this case is very lengthy it will imply that operations of the router are running smoothly.
b. The Configuring Global Parameters
The router has to be in the configuration with global parameters. The following summarized steps facilitates global parameters configuration of the router;
Step 1: configure the terminals of the router
Step 2: provide the hostname of the internet /routing service provider
Step 3: Enable an institutional password that is secret and known only to the administrators.
Step 4: No lookup for the IP domain.
Detailed Global Parameters configuration
- Configuring I/O Memory Allocation
The percentage reallocation of the DRAM that is in use for processor memory and the I/O memory on Cisco 3945E Cisco 3925E routers use “the memory-size iomem i/o-memory-percentage” command configuring the global mode. To revert to the memory alloction that is default, there is the need to use no form of the provided command. The given procedure enables the smartinit.
Note: The Cisco Internet providers recommend is customers to configure size of the memory iomem that is shown below which is 25%. Any value that goes beyond 25% should be used for the enhancement of the performance of the IPSec. When the I/O memory percentage is specified in the line of command, he memory of processor automatically acquires the rest of the percentage of the memory of DRAM.
