The mpls ldp timer igp-sync-delay command sets the interval during which a label switched path (LSP) is being set up after an LDP session is created.
The undo mpls ldp timer igp-sync-delay command restores the default configuration.
By default, the interval is 10 seconds.

Usage Scenario
LDP-Interior Gateway Protocol (IGP) synchronization-enabled devices complete to establish an LDP session earlier than an LSP. The mpls ldp timer igp-sync-delay command can be used to switch traffic to the established LSP after a specified period of time. This setting prevents traffic loss that occurs if the LDP session in the Up state attempts to switch traffic to the LSP that has not been established. Using the default delay value is recommended.
