ip ospf hello-interval
Use this command to specify the interval between hello packets. The no-form of
this command will reset the hello-interval to the default value.
ip ospf hello-interval
SECONDS
no ip ospf hello-interval
Default
10 seconds
Command Mode

Usage Guideline
The hello-interval is advertised in the hello packets. Configure the same hello-
interval for all routers on a specific network. A shorter hello interval ensures
faster detection of topological changes but results in more routing traffic.
When configuring the hello-interval, if the hello-interval*4<=
65535, then the
dead-interval will be automatically updated to hello-interval*4.
Example
The following example shows setting the hello-interval to 3 seconds on interface
VLAN 1.
Verify the settings by entering the
show ip ospf interface
command.
Syntax Description
