9.3.2.5 PIM Hello Message
PIM routers periodically send PIM hello messages to discover neighboring PIM routers
and to determine which router will be the DR for each subnet. PIM hello messages are
also the multicast packets using the group address 224.0.0.13 (all PIM routers group).
To specify an interval to send PIM hello messages, use the following command.
ip pim query-interval <1-18724>
Specifies an interval to send PIM hello messages.
1-18724: hello message interval (unit: second)
Deletes a specified interval to send PIM hello
messages.
PIM hello messages may contain the hold time value in the option fields, which specifies
how long the information is valid. The default hold time is 3.5 times of the interval of the
PIM hello messages. If a hold time you specified is less than the current interval of those,
the hold time will be ignored and return to the default value.
To specify a hold time of PIM hello messages, use the following command.
ip pim query-holdtime
<1-65535>
Specifies a hold time of PIM hello messages.
1-65535: hello message hold time (unit: second)
Deletes a specified hold time of PIM hello messages.
9.3.2.6 PIM Join/Prune Interval
PIM routers periodically send PIM join/prune messages to a group. If a router does not
send the join message during 3 times of the specified interval, it will be pruned from the
group.
To specify an interval to send PIM join/prune messages, use the following command.
ip pim message-interval
<1-65535>
Specifies an interval to send join/prune messages.
1-65535: join/prune message interval (unit: second)
