lmp interface enable

Function

The lmp interface enable command creates an in-band LMP interface, also known as an in-band control channel interface.

The undo lmp interface enable command deletes an in-band LMP interface.

By default, in-band LMP interfaces do not exist in the system.

Usage Guidelines

Usage Scenario

As an extension of MPLS, GMPLS separates the data channel from the control channel. If a fault occurs on the control channel, the data channel will not be affected, and service interruptions can be prevented. This enhances network robustness.

Separation between the control channel and the data channel may be implemented in either of the following modes:

If the control channel and data channel are separated in in-band mode, run the lmp interface enable command on the data channel interface where GMPLS TE is enabled to configure the interface to serve also as the in-band control channel interface.

Configuration Impact

After the lmp interface enable command is run, the system will automatically generate a virtual LMP interface. (The in-band control channel interface is also called the LMP interface.) The number of the LMP interface is the same as that of the physical interface, and the LMP interface automatically borrows the IP address of the physical interface.

Precautions

This command can only be used on IP devices that are connected to optical network devices. Do not use other non-such devices.
