What configuration is needed on R1 to allow communication from LAN1 to LAN2?

The correct answer involves adding a specific route to facilitate communication between two distinct LANs (LAN1 and LAN2) connected through a router (R1). In this context, the route being added with the command targets the destination network of LAN2, which is identified as 192.168.1.0/24.

By specifying the destination address of 192.168.1.0/24 and setting the gateway to 192.168.99.2, R1 is instructed to forward packets destined for LAN2 (192.168.1.0/24) out through the gateway that connects to that network. This is essential for network connectivity, as it allows any devices within LAN1 (presumably operating on a different subnet) to communicate with devices on LAN2. Without this static route, R1 would not know where to send traffic intended for LAN2, leading to a breakdown in communication.

It’s crucial that the route is precisely defined to ensure that the intended traffic is correctly directed, maintaining the efficiency of the network’s data flow. In networking, having the correct routes is vital since they determine how packets find their way to their destinations across different subnets.
