Configuring LDP GR
Before you configure LDP GR, enable LDP on the GR restarter and GR helpers.
The LDP GR configuration is required only on a GR restarter. Because the role (GR restarter or helper) of a device in a GR process is unpredictable, configure LDP GR on all involved devices as a best practice.
To configure LDP GR:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter LDP view. | mpls ldp | N/A |
3. Enable LDP GR. | graceful-restart | By default, LDP GR is disabled. |
4. Set the Reconnect timer for LDP GR. | graceful-restart timer reconnect reconnect-time | By default, the Reconnect time is 120 seconds. |
5. Set the MPLS Forwarding State Holding timer for LDP GR. | graceful-restart timer forwarding-hold hold-time | By default, the MPLS Forwarding State Holding time is 600 seconds. |
