The network infrastructure team wants to add a second router to act as a backup for the primary router that is currently serving as the gateway. In this scenario, the team wants to ensure that the IP address of the gateway is not changed on the devices connected to the network. To accomplish this, the team can use a Virtual IP (VIP) address.
A Virtual IP address is an IP address that is assigned to a network interface or a group of network interfaces, instead of being assigned to a specific device. The IP address is associated with the interface or group, rather than with a particular physical device. This allows multiple devices to share a single IP address, providing redundancy and failover capabilities.
When a VIP is used, devices on the network continue to use the same IP address for the gateway, even if the primary router fails and the backup router takes over as the gateway. The VIP is then moved to the interface of the backup router, allowing it to take over the duties of the primary router.
In this scenario, a VIP can be assigned to the interface of the primary router and the backup router. If the primary router fails, the VIP is automatically moved to the interface of the backup router, which takes over as the gateway. The devices on the network continue to use the same IP address for the gateway, even though the backup router is now providing the service.
A loopback IP address is an IP address that is assigned to a network interface on a device. A loopback address is used to test the networking stack of a device, and is not generally used in a production environment.
A reserved IP address is an IP address that is set aside for a specific purpose, such as for use on a private network. A reserved IP address can be assigned to a device, but it is not used in this scenario.
A public IP address is an IP address that is assigned to a device on the Internet. Public IP addresses are used to identify devices on the Internet, and are not generally used in a local area network.
Therefore, the correct answer is B. Virtual IP.
