ROTOCOL PERATION
By default, the interface does not fill in the MTU field when transmitting DD
packets, and the MTU in the DD packets is 0.
Disabling the Interface to Send OSPF Packets
Use the
silent-interface
OSPF packets.
Perform the following configuration in OSPF View.
Table 158 Disabling the interface to send OSPF packets
Operation
Prevent the interface from
sending OSPF packets
Allow the interface to send
OSPF packets
By default, all the interfaces are allowed to transmit and receive OSPF packets.
After an OSPF interface is set to silent status, the interface can still advertise its
direct route. However, the OSPF hello packets of the interface are blocked, and no
neighboring relationship can be established on the interface. This enhances the
ability of OSPF to adapt to the network, which can reduce the consumption of
system resources. On a Switch, this command can disable/enable the specified
VLAN interface to send OSPF packets.
Configuring OSPF and Network Management System (NMS)
Configuring OSPF MIB binding After multiple OSPF processes are enabled,
you can configure to which OSPF process MIB is bound.
Perform the following configuration in System View.
Table 159 Configure OSPF MIB binding
Operation
Configure OSPF MIB binding
Restore the default OSPF MIB binding
By default, MIB is bound to the first enabled OSPF process.
Configuring OSPF TRAP You can configure the switch to send multiple types
of SNMP TRAP packets in case of OSPF anomalies. In addition, you can configure
the switch to send SNMP TRAP packets when a specific process is abnormal by
specifying the process ID.
