Configure the SPF

5 seconds by default 

 

To prevent OSPF routing information from being acquired by the routers on a certain network, use the 

silent-interface command to disable OSPF packet transmission on the corresponding interface. 

Follow these steps to disable OSPF packet transmission on an interface: 

Enter system view 

— 

Enter OSPF view 

ospf [ process-id [ router-id 
router-id ] ] 

— 

Disable OSPF packet 
transmission on a specified 
interface 

silent-interface 
silent-interface-type 
silent-interface-number 

Required 

By default, all the interfaces are 
allowed to transmit OSPF 
packets. 

 

z 

On the same interface, you can disable multiple OSPF processes from transmitting OSPF packets. 

The  silent-interface command, however, only applies to the OSPF interface on which the 

specified process has been enabled, without affecting the interface for any other process. 

z 

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 adjacencies can be 

established on the interface. This enhances OSPF networking adaptability, thus reducing the 

consumption of system resources. 

 

Follow these steps to configure OSPF authentication: 

Enter system view 

— 

Enter OSPF view 

ospf [ process-id [ router-id 
router-id ] ] 

— 

Enter OSPF area view 

area area-id 

— 

Configure the authentication mode 
of the OSPF area 

authentication-mode { simple 
| md5 }  

Required 

Not configured by default
