Beginning in privileged EXEC mode, follow these steps to set the interval of hello packet transmission.
Command
Purpose
Step 1
config terminal
Enter global configuration mode.
Step 2
Interface
ifName
Enter interface configuration mode.
Step 3
ip ospf hello-interval
seconds
Set the hello interval of the interface
By default, send Hello packets every 10 seconds.
Step 4
exit
Return to global configuration mode.
Step 5
exit
Return to privileged EXEC mode.
Step 6
show ip ospf interface [
vlan-id
]
Verify your entries.
Step 7
Copy
running-config
startup-config
(Optional) Save your entries in the configuration file.
To restore the default hello of the interface, use
no ip ospf hello-interval
interface configuration command.
Setting a dead timer for the neighboring routers
The dead timer of neighboring routers refers to the interval in which a router will regard the neighboring router as
dead if no Hello packet is received from it. The user can set a dead timer for the neighboring routers.
Beginning in privileged EXEC mode, follow these steps to set a dead timer for the neighboring routers.
Command
Purpose
Step 1
config terminal
Enter global configuration mode.
Step 2
Interface
ifName
Enter interface configuration mode.
Step 3
ip ospf dead-interval
seconds
Configure a dead timer for the neighboring routers
By default, the dead interval for the neighboring
routers is 40 seconds.
Step 4
exit
Return to global configuration mode.
Step 5
exit
Return to privileged EXEC mode.
Step 6
show ip ospf interface [
vlan-id
]
Verify your entries.
Step 7
Copy
running-config
startup-config
(Optional) Save your entries in the configuration file.
To restore the default dead interval of the neighboring routers, use
no ip ospf hello-interval
interface configuration
command.
configuring an Interval required for sending LSU packets
Trans-delay seconds should be added to the aging time of the LSA in an LSU packet.Setting the parameter like this
mainly considers the time duration that the interface requires for transmitting the packet.
The user can configure the interval of sending LSU message. Obviously, more attention should be paid on this item
over low speed network.
