Parameters

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. This command displays LDP running parameters for the specified VPN instance. If you do not specify a VPN instance, this command displays LDP running parameters for the public network.

Usage guidelines

This command displays the following LDP running parameters:

Global parameters, which are applicable to all LDP networks.
Instance parameters, which are applicable to a specific LDP network.

Examples

# Display LDP running parameters for the public network.

Table 16: Command output

Field	Description
Global Parameters	LDP running parameters for all LDP-enabled networks.
Protocol Version	LDP protocol version.
IGP Sync Delay on Restart	Maximum delay time (in seconds) that LDP must wait before it notifies IGP of an LDP session-up event when there is an LDP restart.
Nonstop Routing	Whether the nonstop routing feature is enabled: On—Enabled. Off—Disabled.
Nonstop Routing State	LDP NSR state: Ready—NSR is enabled, and LDP session and LSP information has been synchronized to the standby process. If an active/standby switchover occurs, the LDP session stays in Operational state, and the forwarding is not interrupted. Not Ready—NSR is not enabled, or NSR is enabled but LDP session and LSP information synchronization to the standby process is not completed. If an active/standby switchover occurs, the LDP session might not be able to stay in Operational state, and the forwarding might be interrupted.
Graceful Restart	Whether the GR feature is enabled: On—Enabled. Off—Disabled.
Forwarding State Hold Time	MPLS Forwarding State Holding time in seconds.
Reconnect Time	Reconnect time in seconds.
DSCP Value	DSCP value for outgoing LDP packets.
Instance Parameters	LDP running parameters for a VPN instance or public network.
Instance ID	VPN instance ID. For the public network, this field displays 0.
LSR ID	LSR ID of the local device.
Loop Detection	Whether loop detection is enabled: On—Enabled. Off—Disabled.
Hop Count Limit	Hop count limit specified for loop detection.
Path Vector Limit	Path Vector length limit specified for loop detection.
Label Retention Mode	The device supports only the Liberal mode.
Label Distribution Control Mode	Label distribution control mode: Ordered or Independent.
IGP Sync Delay	Delay time (in seconds) that LDP must wait before it notifies IGP of an LDP session-up event.
