Routing Codes For Directly Connected Networks

The routing table also contains a local route for each of its directly connected networks, indicated by the status code of L

For IPv4 local routes the prefix length is /32 and for IPv6 local routes the prefix length is /128

This means the destination IP address of the packet must match all the bits in the local route for this route to be a match

A directly connected network is denoted by a status code of C in the routing table

The purpose of the local route is to efficiently determine when it receives a packet for the interface instead of a packet that needs to be forwarded
