What does the code 'L' in the routing table signify?

In the routing table, the code 'L' signifies 'Local'. This indicates that the route is associated with the device itself, representing an IP address that has been configured on one of its own interfaces. Local routes are not learned from other routers or through routing protocols; they are static entries that inform the routing software about the IP addresses directly assigned to the router's interfaces. Understanding this helps network professionals recognize that local routes are essential for facilitating communication within the local subnet and ensuring that the router knows how to handle traffic addressed to its own interfaces.
