**Table 1** Description of the **display isis ldp-sync interface** command output
Item	Description
Sync State	Status of LDP and IS-IS synchronization: Achieved: Synchronization is complete. HoldDown: The state in which the interface waits to create an LDP session without creating an IS-IS neighbor relationship. HoldMaxCost: IS-IS advertises the maximum cost along an LSP. Init: Initial status.
Interface	Name of the interface connected to the neighbor.
HoldDownTimer	Interval during which an interface waits to create an LDP session before establishing an IS-IS neighbor relationship.
HoldMaxCostTimer	Value of the hold-max-cost timer. The default value is 10s. If infinite is displayed, IS-IS keeps advertising the maximum cost along an LSP before an LDP session is reestablished.
LDP State	Status of an LDP session: GR. Up. Down.
