Path determination occurs
at the network layer
The path determination function enables a router to evaluate the paths to a destination and
to establish the preferred way to handle a packet
The router uses the routing table to determine the best path and then
uses the switching function to forward the packet
The switching function is the internal process used by a router to accept
a packet on one interface and forward it to a second interface on the same router
A key responsibility of the switching function of the router is to
encapsulate packets in the appropriate frame type for the next data link
The router uses the network portion of the address to
make path selections to pass the packet to the next router along the path
