Usage Guidelines

Usage Scenario

After global MPLS is enabled, run the display mpls ldp command to view LDP configurations, including configurations of the GR timer, label distribution, and label management.

Prerequisites

MPLS has been enabled globally using the mpls command, and MPLS LDP has been enabled globally using the mpls ldp command.

Example

# Display global LDP configurations.

<HUAWEI> display mpls ldp

**Table 1** Description of the display mpls ldp command output
Item	Description
LDP Global Information	Global LDP information.
Protocol Version	LDP protocol version.
Neighbor Liveness	Timeout period of the GR Neighbor-liveness timer. To set the timeout period of the GR Neighbor-liveness timer, run the graceful-restart timer neighbor-liveness command.
Graceful Restart	Whether LDP is enabled with GR: On: GR is enabled. Off: GR is disabled. To enable LDP GR, run the graceful-restart command.
FT Reconnect Timer	Timeout period of the GR reconnect timer. To set the timeout period of the GR reconnect timer, run the graceful-restart timer reconnect command.
MTU Signaling	Whether the MTU signaling is enabled: On: The private MTU TLV is sent. Off: The MTU TLV is not supported. On(apply-tlv): The MTU TLV is sent according to RFC 3988. To set the MTU signaling, run the mtu-signalling command.
Recovery Timer	Timeout period of the GR Recovery timer. To set the timeout period of the GR Recovery timer, run the graceful-restart timer recovery command.
Capability-Announcement	Status of the LDP dynamic capability announcement function: On: LDP dynamic capability announcement is enabled. Off: LDP dynamic capability announcement is disabled. NOTE: The switch does not support this parameter.
Longest-match	Status of LDP extension for inter-area LSP: On: LDP extension for inter-area LSP is enabled. Off: LDP extension for inter-area LSP is disabled. To set the status of LDP extension for inter-area LSP, run the longest-match command.
mLDP P2MP Capability	Whether mLDP P2MP is globally enabled: On: mLDP P2MP is enabled globally. Off: mLDP P2MP is disabled globally. NOTE: The switch does not support this parameter.
mLDP MBB Capability	Whether the mLDP make-before-break capability is enabled: On: mLDP make-before-break is enabled. Off: mLDP make-before-break is disabled. NOTE: The switch does not support this parameter.
mLDP MP2MP Capability	Whether multipoint extensions for LDP (mLDP) multipoint-to-multipoint (MP2MP) is globally enabled: On: mLDP MP2MP is enabled globally. Off: mLDP MP2MP is disabled globally. NOTE: The switch does not support this parameter.
LDP Instance Information	Information about the LDP multi-instance.
Instance ID	ID of a VPN instance in the integer format.
VPN-Instance	Name of a VPN instance. The default name is null. NOTE: The switch does not support this parameter.
Instance Status	Status of an instance: Active: The instance is in the Active state. NotInService: The instance is in the NotInService state temporarily due to certain operations. For example, after the reset mpls ldp or graceful-restart command is used, the instance is unavailable temporarily. Destroy: The instance is in the Destroy state. For example, after the undo mpls ldp command is used, the instance is in the Destroy state.
LSR ID	LSR ID of an LDP instance.
Loop Detection	Loop detection status: On: Loop detection is enabled. Off: Loop detection is disabled. To set the status of the loop detection, run the loop-detect command.
Path Vector Limit	Path vector limit for loop detection. To set the path vector limit for loop detection, run the path-vectors command.
Label Distribution Mode	Label distribution mode: Ordered Independent Currently, the switch supports only the ordered mode.
Label Retention Mode	If label advertisement mode is DU, label retention mode will be Liberal. If label advertisement mode is DOD, label retention mode will be Conservative.
Instance Deleting State	Deletion status of an instance: Yes: The instance is being deleted. No: The instance is not being deleted.
Instance Resetting State	Resetting status of an instance: Yes: The instance is being reset. No: The instance is not being reset.
Graceful-Delete	Whether graceful deletion is enabled: On: enables graceful deletion. Off: disables graceful deletion. NOTE: The switch does not support this parameter.
Graceful-Delete Timer	Value of the Graceful-delete Timer, in seconds.
