In addition to configuration information, you can display the following LDP-IGP synchronization information.
To display LDP-IGP synchronization, use the show mpls ldp session command. When the timers are running, the remaining time appears without a refresh as well as the static value of the timer.
device# show mpls ldp session 10.7.7.2 0
Peer LDP ID: 10.7.7.2:0, Local LDP ID: 10.1.7.1:0, State: Operational

To display whether LDP-IGP synchronization is enabled on the interface, use the show mpls ldp interface command.

To display the current cached LDP-IGP synchronization state, use the show mpls interface command.
