Add an "on-link" routing entry

As an IT administrator, it is important to have an understanding of how to add an on-link routing entry. This is one of the basic functions of a network administrator. On-link routing is the process of routing packets between two or more networks, such as two or more physical networks or two or more virtual networks. With on-link routing, the packet will be routed directly between the two networks without the need for additional routing devices or services.

In order to add an on-link routing entry, the network administrator must first determine the address of the destination network. This can be done by using a network address translation (NAT) table, or by using a routing protocol such as RIP or OSPF. Once the destination address has been determined, the administrator can then add the route to the routing table. The route can be added by using the command line interface (CLI) or by using a graphical user interface (GUI) such as a web-based GUI.

When adding a route, the administrator will need to provide the network address of the destination network, as well as the network mask. The network mask is used to define the range of IP addresses that will be reachable from the route. The administrator must also provide the IP address of the next hop, which is the IP address of the device or service that will be used to route the packet to the destination network.

In addition to the network address and mask, the administrator will also need to provide the metric, which is the cost associated with using the route. A higher metric indicates a higher cost, and a lower metric indicates a lower cost. The administrator may also need to specify other options, such as the type of routing protocol that will be used for the route.

Once the route has been added to the routing table, the administrator will need to enable the route. This can be done by enabling the route at the interface level, or by enabling it through the routing protocol. When the route has been enabled, the administrator will need to verify that it is functioning correctly. This can be done by using the ping command or by using a traceroute command.

On-link routing is a basic function of any network administrator, and is essential for routing packets between networks. By understanding how to add an on-link routing entry, an IT administrator can ensure that the network is functioning properly and efficiently.
