Command Reference Guide
ip pim-sparse hello-timer <value>
Use the ip pim-sparse hello-timer command to specify protocol-independent multicast (PIM) sparse hello
timer period. This is the time interval at which periodic hellos are sent out on all interfaces of a
PIM-capable router. Use the no form of this command to return to the default value.
Syntax Description
<value>
Default Values
By default, the hellos are transmitted on PIM interfaces every 60 seconds.
Command History
Release 11.1
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 number 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 be sent on the high level data link control (HDLC) 1 interface every
3600 seconds:
(config)#interface hdlc 1
(config-hdlc 1)#ip pim-sparse hello-timer 3600
60000CRG0-35E
Specifies the interval (in seconds) at which periodic hellos are sent out of
the interface. Valid range is 10 to 3600 seconds.
