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.
Network Type
Set the network type for the interface, which can be Broadcast, NBMA, P2P, or P2MP
The default network type of an interface depends on the link layer protocol of the
interface:
• If the link layer protocol is Ethernet or FDDI, the network type of the interface
defaults to Broadcast.
• If the link layer protocol is ATM, Frame Relay, or X.25, the network type of the
interface defaults to NBMA.
• If the link layer protocol is PPP, LAPB, HDLC, or POS, the network type of the
interface defaults to P2P.
DR Priority
Set the router priority of the interface for DR/BDR election.
Routers in a network elect the DR and BDR according to their router priorities. The
bigger the value, the higher the priority. If a device has a priority of 0, it will not be
elected as a DR or BDR.
Authentication Mode 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
1. Select Network > Routing Management > OSPF from the navigation tree.
The OSPF configuration page appears.
2. After you complete OSPF area configurations, click Show Interface on the Show Information tab.
