Item Description
Hello Interval
Set the interval for sending hello packets.
The hello interval on P2P, Broadcast interfaces defaults to 10 seconds and defaults
to 30 seconds on P2MP and NBMA interfaces.
The smaller the hello interval is, the faster the network converges and the more
network resources are consumed.
The interfaces on a specific network segment must have the same Hello interval.
Dead Interval
Set the OSPF dead interval.
Within the dead interval, if the interface receives no hello packet from the neighbor,
it declares that the neighbor is down.
The default dead interval is 40 seconds on P2P, Broadcast interfaces and 120
seconds on P2MP and NBMA interfaces.
The dead interval should be at least four times the hello interval on an interface. The
interfaces on a specific network segment must have the same dead interval.
Authentication Mode
Key String
Key ID
Set the authentication mode and parameters for authenticating OSPF packets on the
interface.
• If the Authentication Mode is null, the interface does not authenticate OSPF
packets, and the Key String and Key ID are not required.
• If Simple is specified for Authentication Mode, the interface authenticates
OSPF packets using simple text key. You need to configure a Key String in
simple text. When you view the configuration file, the authentication key is
displayed in simple text.
• If MD5 is specified for Authentication Mode, the interface authenticates
OSPF packets using MD5 authentication. You need to configure a Key String in
cipher text and a Key ID.
• If HMAC-MD5 is specified for Authentication Mode, the interface
authenticates OSPF packets using HMAC-MD5 authentication. You need to
configure a Key String in cipher text and a Key ID.

Displaying OSPF Interface Information
Select Network > Routing Management > OSPF from the navigation tree to enter the OSPF
configuration page. After you complete OSPF area configurations, click Show Interface on the Show
Information tab to display the OSPF interface information, as shown in
Figure 25 .
