DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide Example This example shows how to configure the keep-alive hold-time to 60 seconds. Switch# configure terminal Switch(config)# mpls ldp configuration Switch(config-ldp)# keepalive-holdtime 60 Warning: The configuring will lead to LDP sessions restart. Switch(config-ldp)# 78-15 label-retention-mode This command is used to configure the label retention mode. Use the no form of this command to revert to the default setting. label-retention-mode {liberal | conservative} no label-retention-mode Parameters liberal conservative Specifies the liberal label retention mode. Specifies the conservative label retention mode. Default By default the label retention mode is configured as liberal. Command Mode LDP Configuration Mode. Command Default Level Level: 12. Usage Guideline If the label distribution method is downstream-unsolicited and the label retention mode is conservative, once the LSR receives label bindings from LSRs which are not its next hop for that Forwarding Equivalence Class (FEC), it discards such bindings. If the label retention mode is liberal, it maintains such bindings. It helps to speed up the setup of Label Switched Paths (LSPs) in case there is a change in the next hop. Example This example shows how to configure the label retention mode to conservative. Switch# configure terminal Switch(config)# mpls ldp configuration Switch(config-ldp)# label-retention-mode conservative Warning: The configuring will lead to LDP sessions restart. Switch(config-ldp)# 78-16 loop-detection This command is used to enable loop detection. Use the no form of this command to disable loop detection. 997
