This command displays information about how to forward packets that arrive labeled as MPLS packets. As such, it shows how labels advertised to upstream peers are mapped to labels received from downstream peers. This mapping is sometimes referred to as the Incoming Label Map (ILM).
When the label_number parameter is omitted, summary information is displayed for all incoming label assignments that have been made by the switch. When the label_number is specified, summary information is displayed for the specified label.
As can be seen below, the output display differs for label mappings signaled by LDP and RSVP-TE. Please see the respective sections for additional information.
