Which configuration automatically leads to the addition of Connected and Local routes?

Configuring an interface with an IP address automatically leads to the addition of Connected and Local routes in a routing table because when an IP address is assigned to an interface, the router recognizes this as a directly connected network.

Connected routes are defined as networks that are directly attached to the router through its interfaces. When you assign an IP address to an interface, the router generates a Connected route for that specific subnet, allowing the router to know that it can reach that network via the assigned interface.

Local routes, on the other hand, are specific to the IP addresses assigned to the interfaces on the router. These routes help in directing traffic destined for the router's own interface.

The other contexts, such as configuring an interface without an IP address, changing the router's firmware, or resetting the routing table, do not inherently create Connected or Local routes. An interface without an IP would not provide routing capabilities; changing firmware does not affect routing configurations, and resetting the routing table would clear existing routes but not generate new ones.
