None

Use the ospf mtu-enable command to enable an interface to add the real MTU 
into DD packets.

Use the undo ospf mtu-enable command to restore the default.

By default, an interface adds an MTU value of 0 into DD packets, that is, no real 
MTU is added.

Note that:

■

After a virtual link is established via a Virtual-Template or Tunnel, two devices 
on the link from different vendors may have different MTU values. To make 
them consistent, set the attached interface’s default MTU to 0.

■

This configuration is not supported on the NULL interface.

# Enable the interface to add the real MTU value into DD packets.
