Default Configuration
The default IP Interface dead-interval time is 40 seconds.
Command Mode
IP Interface Configuration
User Guidelines
The interval is advertised in router hello packets. This value must be the same for all routers
and access servers on a specific network.
Example
The following example defines the OSPF dead-interval time of 100 seconds on interface
1.100.100.100.
Console(config)# interface ip 1.100.100.100
Console(config-ip)# ospf dead-interval 100
ospf retransmit-interval
The ospf retransmit-interval interface configuration command specifies the time between link-
state advertisement (LSA) retransmissions for interface adjacencies belonging to the interface. To
return to the default value, use the no form of this command.
Syntax
ospf retransmit-interval seconds
no ospf retransmit-interval
seconds—Time (in seconds) between retransmissions. The time must be greater than the
•
expected round-trip delay between any two routers on the attached network.
(Range: 1 - 3600)
Default Configuration
The default time is 5 seconds.
Command Mode
IP Interface Configuration
User Guidelines
When a router sends an LSA to its neighbor, it keeps the LSA until it receives back the
acknowledgment message. If the router receives no acknowledgment, it resends the LSA.
Setting this parameter should be conservatively configured, or unnecessary retransmission can
result.
