To configure OSPF authentication, you need to configure the same area authentication mode on all the 

routers in the area. In addition, the authentication mode and password for all interfaces attached to the 

same area must be identical. 

Follow these steps to configure OSPF authentication: 

Enter system view 

— 

Enter OSPF view 

ospf [ process-id | router-id router-id | 
vpn-instance instance-name ] * 

— 

Enter area view 

area area-id 

— 

Configure the authentication 
mode 

authentication-mode { md5 | simple }

Required 

Not configured by 
default. 

Exit to OSPF view 

— 

Exit to system view 

— 

Enter interface view 

interface interface-type 
interface-number 

— 

Configure the authentication 
mode (simple authentication) 
for the interface 

ospf authentication-mode simple 
[ cipher | plain ] password 

Configure the authentication 
mode (MD5 authentication) for 
the interface 

ospf authentication-mode 
{ hmac-md5 | md5 } key-id [ cipher | 
plain ] password 

Either is required. 

Not configured by 
default. 

 

Generally, when an interface sends a DD packet, it adds 0 into the Interface MTU field of the DD packet 

rather than the interface MTU.  

Follow these steps to add the interface MTU into DD packets: 

Enter system view 

— 

Enter interface view 

interface interface-type 
interface-number 

— 

Enable OSPF to add the 
interface MTU into DD packets 

ospf mtu-enable 

Optional 

Not enabled by default; that is, 
the interface fills in a value of 0.
