By default, The MTU value is 0 when the interface sends DD packets, i.e. the 
actual MTU value of the interface is not written.

Database Description (DD) packets are used to describe its own LSDB when the 
router running OSPF protocol is synchronizing the database.

The default MTU value of DD packet is 0. With this command, the specified 
interface can be set manually to write the MTU value area in DD packets when 
sending DD packets, namely, the actual MTU value of the interface is written in.

# Set interface Vlan-interface 3 to write MTU value field when sending DD 
packets.

Interface view

broadcast: Changes the interface network type to broadcast.

nbma: Changes the interface network type to NBMA.

p2mp: Changes the interface network type to p2mp.

p2p: Changes the interface network type to point-to-point.

Use the ospf network-type command to configure the network type of OSPF 
interface. Use the undo ospf network-type command to restore the default 
network type of the OSPF interface.

■

Broadcast: If Ethernet or FDDI is adopted, OSPF defaults the network type to 
broadcast.

Related command: ospf dr-priority.
