(Optional) Setting the Delay Timer Value
Context
When an LDP session is reestablished on a faulty link, LDP starts the Delay timer to wait for the establishment of an LSP. After the Delay timer times out, LDP notifies the IGP that synchronization between LDP and IGP is complete.
Procedure
- Run system-view
The system view is displayed.
- Run interface interface-type interface-number
The interface view is displayed.
- (Optional) On an Ethernet interface, run undo portswitch
The interface is switched to Layer 3 mode.
By default, an Ethernet interface works in Layer 2 mode.
Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, and S6730S-S support switching between Layer 2 and Layer 3 modes.
- Run mpls ldp timer igp-sync-delay value
The period of waiting for the LSP setup after the establishment of the LDP session is set.
By default, the value of the delay timer is 10s.
