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.
