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
ospf network-type
Use ospf network-type to set the network type for an interface.
Use undo ospf network-type to restore the default network type for an interface.
Syntax
ospf network-type { broadcast | nbma | p2mp [ unicast ] | p2p }
undo ospf network-type
Default
By default, the network type of an interface depends on its link layer protocol:
• For Ethernet and FDDI, the network type is broadcast.
• For ATM, FR, and X.25, the network type is NBMA.
• For PPP, LAPB, HDLC, and POS, the network type is P2P.
