DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide 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. Switch# configure terminal Switch(config)# mpls ldp configuration Switch(config-ldp)# graceful-restart neighbor-liveness timer 180 Switch(config-ldp)# 78-14 keepalive-holdtime This command is used to configure the keep-alive hold-time for LDP sessions. Use the no form of this command to revert to the default setting. keepalive-holdtime SECONDS no keepalive-holdtime Parameters SECONDS Specifies the keep-alive hold-time in seconds. The range is from 15 to 65535 seconds. Default By default, this value is 40 seconds. Command Mode LDP Configuration Mode. Command Default Level Level: 12. Usage Guideline This command is used to configure the LDP session keep-alive hold-time. LDP maintains a keep-alive hold timer for each peer session. If the keep-alive hold timer expires without receipt of an LDP PDU from the peer, LDP terminates the LDP session. Each LSR sends keep-alive messages at regular intervals to its LDP peers to keep the sessions active. The keep-alive interval is one third of the keep-alive hold-time. 996
