Usage Guidelines

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.

Example

# After the LDP session is established on VLANIF100, the interval is set to 15 seconds, during which the LSP is being set up.
