(Optional) Setting the Delay Timer Value
Context
When an LDP session or LDP adjacency 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.
Setting the Delay timer value in the interface view
You can set the Delay timer value on a specified interface. This mode applies to the scenario where a few interfaces need to use the Delay timer.
Setting the Delay timer value in the MPLS LDP view
After you set the Delay timer value in the MPLS LDP view, the Delay timers on all interfaces in the MPLS LDP view are set to this value. This mode applies to the scenario where many interfaces on a node need to use the Delay timer.
Procedure
- Perform the following steps in the MPLS-LDP view.
- Perform the following steps in the interface view.
- 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.
The mode switching function takes effect when the interface only has attribute configurations (for example, shutdown and description configurations). Alternatively, if configuration information supported by both Layer 2 and Layer 3 interfaces exists (for example, mode lacp and lacp system-id configurations), no configuration that is not supported after the working mode of the interface is switched can exist. If unsupported configurations exist on the interface, delete the configurations first and then run the undo portswitch command.
If many Ethernet interfaces need to be switched to Layer 3 mode, run the undo portswitch batch interface-type { interface-number1 [ to interface-number2 ] } &<1-10> command in the system view to switch these interfaces to Layer 3 mode in batches.
