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
Release A4.01
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 MEF Ethernet 0/1 interface every 3600 seconds:
(config)#interface mef-ethernet 0/1
(config-mef-ethernet 0/1)#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.
Command was introduced.
Command was expanded to include the Metro Ethernet Forum (MEF)
Ethernet interface.
