Using unique local addresses can help prevent external systems from having direct access to your internal systems. They are not routable on the global Internet. These addresses can only be used within a specified organization. They are similar to вЂњprivateвЂќ IPv4 addresses. Unique local addresses are a set of addresses that are intended for use in internal networks. So, during a normal startup process, an IPv6 system will obtain a link-local address before it receives a regular, routable IP address. IPv6 system must have a link-local address in order for some of internal protocol functions to work properly. In IPv6 link-local addresses may be assigned by the stateless address autoconfiguration process. The bottom 64В bits used for the address are random. In IPv6, the address block fe80::/64 has been reserved for link-local addresses. Link-local addresses allow you to have network connectivity until another more suitable address can be obtained. These addresses were used by the DHCP autoconfiguration service on a system when a DHCP address could not be obtained. They existed in the address block 169.254.0.0/16. Link-local addresses also existed in IPv4. Routers will not route link-local addresses. Link-local addresses are intended to only be used on a single network segment or subnet. The loopback address in IPv4 is 127.0.01. It is an internal address that routes back to the local system. The loopback address, also called localhost, is probably familiar to you. We will cover the loopback address, link-local addresses, and unique local addresses. These addresses or groups of addresses serve very specific function. There are several special addresses in IPv6.

How to Add a Virtual Network Card in Windows в‡’ Video Pinging the Loopback card as shown in the following image must be successful! Similarly, test the connection by pinging the Cisco Router FastEthernet 0/0 interface from your physical computer. Then, test the connection by pingingВ the loopback IP address.Д¬loud1 and Cisco Router can communicate with each other. The Loopback network card will become selectable as you can see in the image below.ДЄssign an IP address to the Cisco Router FastEthernet 0/0 interface and turn it on. To cable Cloud1 and Cisco Router, click cabling and then click Cloud1. Once you have selected the GNS3Loopback adapter, click the Add button.ДЄfter successfully completing the loopback network card insertion steps, click OK to save the settings. In the Cloud1 configuration window, you need to select the Loopback network card you added in the Ethernet Interfaces section. Click Right-Click / Configure to set up Cloud1. Restart your computer before proceeding to step 12!ДЄfter restarting your computer, run the GNS3 program and create a new project.Дrag and drop one Router and Cloud into the GNS3 workspace. You can check the configuration by clicking the Details button on the network card. After configuring the IP address settings, click OK to save the settings. You can change the IP address settings here. You need to set an IP address for the GNS3Loopback network card. You can rename the Loopback card to avoid confusing it with other network cards. You can see that the loopback card has added successfully. In this window, click Next to continue.ДЄdding hardware is complete and click Finish to close the window. The following window provides a summary of the hardware to be installed. Select Microsoft from the Manufacturer section, and then select Microsoft KM-TEST Adapter from the right pane. In the Hardware Types window, select Network Adapters and click the Next button. The hdwwiz command is a short way to add an Adapter.ДЄfter the hardware wizard opens, click Next to continue.Д¬ontinue by selecting Advanced as we will add the Loopback card manually. On Windows 10, open the Run window and type hdwwiz and click OK.
