OSPF Protocol Configuration Mode
router-id <router_id>
no router-id
Configures the ID number for the layer3
switch running OSPF; the “no router id”
command cancels the ID number. The IP
address of an interface is selected to be the
layer3 switch ID. (optional)
[no] network {<network> <mask> |
<network>/<prefix>} area <area_id>
Configure certain segment to certain area,
the no [no] network {<network> <mask> |
<network>/<prefix>} area <area_id>

2. Configure OSPF protocol parameters
（1）Configure OSPF packet sending mechanism parameters
1）Configure OSPF packet verification
2）Set the OSPF interface to receive only
3）Configure the cost for sending packets from the interface
Command
Explanation
Interface Configuration Mode
ip ospf authentication
{ message-digest | null}
no ip ospf authentication

interfaces; the no action of this command
restores the default settings.
[no] passive-interface <ifname>
[<ip-address>]
Sets an interface to receive only, the no
passive-interface <ifname>[<ip-address>]
command cancels this configuration.
ip ospf cost <cost >
no ip ospf cost
Sets the cost for running OSPF on the interface;
the no ip ospf cost
command restores the
default setting.
