DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide Command Default Level Level: 12. Usage Guideline If LDP graceful restart is enabled and an LDP session is re-established, the device shall complete the exchange of the label mapping information with its neighbor within the recovery time. After the recovery time expires, the device will delete all label forwarding entries that are marked as stale. Example This example shows how to configure the recovery time to 500 seconds. Switch# configure terminal Switch(config)# mpls ldp configuration Switch(config-ldp)# graceful-restart recovery timer 500 Switch(config-ldp)# 76-13 graceful-restart neighbor-liveness timer This command is used to configure the LDP graceful restart neighbor liveness time. Use the no form of this command to revert to the default setting. graceful-restart neighbor-liveness timer SECONDS no graceful-restart neighbor-liveness timer Parameters SECONDS Specifies the neighbor liveness time in seconds. The range is from 5 to 300 seconds. Default By default, this value is 120 seconds. Command Mode LDP Configuration Mode. Command Default Level Level: 12. Usage Guideline When the Switch detects that its LDP session with a neighbor is down, it tries to re-establish LDP communication with the neighbor within the re-connection time. The re-connection time is set according to the lesser of the Fault Tolerant (FT) reconnect timeout advertised by the neighbor and the local neighbor liveness time. If the LDP session cannot be established within the reconnection time, all associated stale label forwarding entries will be deleted. If LDP graceful restart is enabled, the advertised FT reconnect timeout is set according to the neighbor liveness time value. Example This example shows how to configure the neighbor liveness time to 180 seconds. 960
