time interval can be configured in several ways
The following lists are sort of time interval which can be configured by user:
• Hello Interval
OSPF router sends Hello packet to notify existence of itself. Hello interval is that
packet transmission interval.
• Retransmit Interval
When router transmits LSA, it is waiting for approval information come from receiver.
In this time, if there is no answer from receiver for configured time, the router trans-
mits LSA again. Retransmit-interval is configuration of the time interval between
transmission and retransmission.
• Dead Interval
If there is no hello packet for the configured time. The router perceives other router is
stopped working. Dead interval is configuration of the time interval which perceives
other router is stopped operating.
• Transmit Delay
When a router transmits LSA, the traffic can be delayed by status of communications.
Transmit delay is considering of the configuration for LSA transmission time.
The interval explained as above must be consistent across all routers in an attached
network.
To configure a Hello interval, use the following command.
ip ospf hello-interval <1-65535>
Configures a Hello interval in the unit of second.
1-65535: interval value (default: 10)
ip ospf A.B.C.D hello-interval <1-
65535>
no ip ospf hello-interval
Sets a Hello interval to the default value.
no ip ospf A.B.C.D hello-interval
To configure a retransmit interval, use the following command.
ip ospf retransmit-interval <1-
65535>
Configures a retransmit interval in the unit of second.
1-65535: interval value (default: 5)
ip ospf A.B.C.D retransmit-
interval <1-65535>
no ip ospf retransmit-interval
Sets a retransmit interval to the default value.
no ip ospf A.B.C.D retransmit-
interval
To configure a dead interval, use the following command.
