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, restore the 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 VLAN-interface 10 to add the interface MTU value into DD packets.
<Sysname> system-view [Sysname] interface vlan-interface 10 [Sysname-Vlan-interface10] ospf mtu-enable
