In the routing table, what does the code 'C' represent?

In the routing table, the code 'C' represents connected routes. This indicates that the network is directly connected to the router and is reachable without the need for any intermediary devices or protocols. Connected routes are automatically added to the routing table when an interface on the router is configured with an IP address and is in an up state.

Since these routes are directly associated with the router's interfaces, they are generally considered the most reliable form of routing information, as the router itself can directly communicate with these local networks. This foundational understanding of how connected routes function is essential for network design and troubleshooting. The other options listed do not accurately represent any standard codes used in a routing table, reinforcing that 'C' is correctly interpreted as connected.
