When connecting a local area network (LAN) to another LAN, which statement is typically true?

When connecting a local area network (LAN) to another LAN, the statement indicating that only one router may represent a LAN to the other network is typically true. The role of a router in this scenario is to manage and route traffic between the two networks, ensuring that data packets can effectively flow from one LAN to another.

Having a single router represent a LAN helps maintain a clear point of management for network traffic, simplifying routing protocols and reducing the potential for routing conflicts. This centralized approach allows for better control over traffic, easier troubleshooting, and a more straightforward configuration, thereby enhancing network performance.

In contrast, having multiple routers directly representing a LAN could lead to complexities and inefficiencies, such as routing loops or inconsistent routing tables, making network management more challenging. Additionally, requiring a dedicated public IP for the LAN, while potentially necessary for internet access, does not reflect the foundational principles of how two LANs connect to each other through routers. Thus, the notion of limiting representation to a single router stands out as the most straightforward and stable approach in such configurations.
