Usage guidelines
After a virtual link is established through a Virtual-Template or Tunnel, two devices on the link from
different vendors might have different MTU values. To make them consistent, set the attached interfaces’
MTU to the default value 0.
After you configure this command, the interface checks whether the MTU in a received DD packet is
greater than its own MTU. If yes, the interface discards the packet.
Examples
# Enable the interface to add the real MTU value into DD packets.
