Configuring To Fill The Mtu Field When An Interface Transmits Dd Packets; Configuring Ospf Network Management System (Nms) - H3C S7500 Series Operation Manual

H3C S7500 Series Ethernet Switches
Configure the
authentication mode of
the OSPF interface
Note:
OSPF supports packet authentication and receives only those packets that are
successfully authenticated. If packet authentication fails, no neighboring
relationship will be established.
The authentication modes for all routers in an area must be consistent. The
authentication passwords for all routers on a network segment must also be
consistent.
4.7.7 Configuring to Fill the MTU Field When an Interface Transmits DD
Packets
By default, an interface uses value 0 instead of its actual MTU value when
transmitting DD packets. After the following configuration, the actual MTU value of the
interface is filled in the Interface MTU field of the DD packets.
Follow these steps to configure the MTU field to be filled when an interface transmits
DD packets

By default, the MTU value
is 0 when an interface
transmits DD packets.
That is, the actual MTU
value of the interface is
not filled in.
