Parameters
None
Description
Use ospf mtu-enable to enable an interface to add the real MTU into DD packets.
Use undo ospf mtu-enable to restore the default.
By default, an interface adds a MTU of 0 into DD packets, which means no real MTU is added.
• 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
interfaces' default MTU to 0.
• After this command is configured, upon receiving a DD packet, the interface checks whether the
MTU in the 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.
