OSPF Network Adjustment and Optimization
319
■
After an OSPF interface is set to be in silent status, the interface can still
advertise its direct route. However, the Hello packets from the interface will be
blocked, and no neighboring relationship can be established on the interface.
This enhances OSPF networking adaptability, thus reducing the consumption of
system resources.
Configuring OSPF
Authentication
n
■
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.
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.

DD packets. That is, the actual
MTU value of the interface is
not filled in.
