ip pim-sparse hello-timer <time>
Use the ip pim-sparse hello-timer command to set the time interval at which periodic hello messages are
transmitted out the interface. Each PIM interface has an independent hello-timer. Use the no form of this
command to return to the default value.
Syntax Description
<time>
Default Values
By default, hellos are transmitted on PIM interfaces every 60 seconds.
Functional Notes
Hello messages are used to inform neighbors of a router's presence. Hello messages normally generate a
small amount of traffic on an interface. Setting the hello-timer to a small interval increases the amount of
hellos sent (thus increasing the amount of traffic). Set the hello-timer to a reasonable value, taking into
consideration the bandwidth available on the interface.
Usage Examples
The following example specifies hellos to be sent on the loopback interface every 3600 seconds:
ProCurve(config)#interface loopback 1
ProCurve(config-loop 1)#ip pim-sparse hello-timer 3600
5991-2114
Specifies the interval (in seconds) at which periodic hellos are sent out the
interface. Valid range is 10 to 3600 seconds.
