The diagram below represents a MPLS network. A packet arrives and then through MPLS$$s

routers, it is moved to the destination IP address. The diagram also shows router tables

that contain mappings between labels and output interfaces. IN LABEL contains label

values for arriving packets, ADDRESS PREFIX is for different reachable destinations, OUT

INTERFACE is the output interface, OUT LABEL is label values added to outbound packets

through this interface.
