Table 116 describes the significant fields shown in the display.
If LDP-IGP synchronization is not enabled on an interface, the output looks like the following:
Router# show mpls ldp igp sync
Ethernet5/1:
LDP configured; LDP-IGP Synchronization not enabled.
The following is sample output from the show mpls ldp igp sync command when you configured a
time delay for MPLS LDP-IGP synchronization:
Router# show mpls ldp igp sync
Ethernet0/0:
LDP configured; LDP-IGP Synchronization enabled.
Sync status: sync achieved; peer reachable.
Sync delay time: 20 seconds (10 seconds left)
IGP holddown time: infinite.
IGP enabled: OSPF 1
