Configuration Commands
only be advertised after the timer expired. Also, the new cost value will be advertised after the user
executes any of the following commands if the currently advertised cost is different:
If the user changes the value of the LDP synchronization timer parameter, the new value will take
effect at the next synchronization event. In other words, if the timer is still running, it will continue
using the previous value.
If parallel links exist to the same neighbor, then the bindings and services should remain UP as long
as there is one interface that is UP. However, the user configured LDP synchronization timer still
applies on the failed then restored interface. In this case, it will only consider this interface for
forwarding after IGP re-advertized its actual cost value.
Note that the LDP Sync Timer State is not always synched across to the standby CPM, so after an
activity switch the timer state might not be same as it was on the previous active CPM.
The no form of this command disables IGP/LDP synchronization and deletes the configuration
Default no ldp-sync-timer
