Enabling Synchronization Between LDP and IGP
Context
Enable this function in the interface view.
This mode allows synchronization between LDP and IGP to be enabled on interfaces. This mode applies to the scenario where a few interfaces need to support this function.
Enable this function in an IGP process.
This mode allows synchronization between LDP and IGP to be enabled on all interfaces in the IGP process. This mode applies to the scenario where many interfaces on a node need to support this function.
Procedure
- If OSPF is used as an IGP, perform the
following steps:
Enable synchronization between LDP and OSPF on an interface.
- 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.

the following steps:
Enable synchronization between LDP and IS-IS on an interface.
