display ospf ldp-sync

Function

The display ospf ldp-sync command displays the status of LDP and OSPF synchronization on an interface.

Format

display ospf ldp-sync interface { all | interface-type interface-number }

Parameters

Parameter	Description	Value
all	Displays information about the synchronization status on all interfaces enabled with LDP and OSPF synchronization.	-
interface-type interface-number	Displays information about the synchronization status on a specified interface.	-

Views

All views

Default Level

1: Monitoring level

Usage Guidelines

For all interfaces that are enabled with LDP and OSPF synchronization, run the display ospf ldp-sync command to view information about the status of LDP and OSPF synchronization.

Example

# Display information about the status of LDP and OSPF synchronization on a specified interface.

<sysname> display ospf ldp-sync interface GigabitEthernet 0/0/1

 Interface GigabitEthernet0/0/1

 HoldDown Timer: 9         HoldMaxCost Timer: 50

 LDP State: Up             OSPF Sync State: Sync-Achieved

**Table 1** Description of the **display ospf ldp-sync interface** command output
Item	Description
Interface	Interface connected to neighbors
HoldDown Timer	Interval at which the interface waits to create an LDP session without creating the OSPF neighbor relationship The default interval is 10 seconds.
HoldMaxCost Timer	Interval at which OSPF advertises the maximum metric in link state advertisements (LSAs) sent by the local device The default interval is 10 seconds. NOTE: If the value of this field is infinite, OSPF keeps advertising the maximum metric value in LSAs sent by the local device before the LDP session is reestablished.
LDP State	Status of an LDP session: Up Down
OSPF Sync State	Status of LDP and OSPF synchronization: Sync-Achieved: indicates that the creation of an LDP session and establishment of the OSPF neighbor relationship are synchronized. HoldDown: indicates the state, in which the interface waits to create an LDP session without creating the OSPF neighbor relationship. HoldMaxCost: indicates that OSPF advertises the maximum metric in LSAs or label switched paths (LSPs) sent by the local device. Init: indicates the initial state.
