The pim ipv6 holdtime join-prune command sets the holdtime in a Join/Prune message sent by the PIM interface.
The undo pim ipv6 holdtime join-prune command restores the default value of the holdtime.
By default, the holdtime in a Join/Prune message sent by the PIM interface is 210 seconds.
| Parameter | Description | Value |
|---|---|---|
| interval | Specifies the value of holdtime in a Join/Prune message sent by the PIM interface. | The value is an integer that ranges from 1 to 65535, in seconds. |

Usage Scenario
After receiving a Join/Prune message from the downstream device, the switch starts the hold timer. If this message carries group-join information and the switch does not receive subsequent Join/Prune messages from the downstream device when the timer expires, it suppresses multicast data forwarding to downstream interfaces of the specified group. If Join/Prune message carries group-prune information, the switch resumes multicast data forwarding to downstream interfaces when the hold timer expires.
Prerequisites
IPv6 multicast routing has been enabled using the multicast ipv6 routing-enable command in the system view.
Precautions
The pim ipv6 holdtime join-prune command has the same function as the holdtime join-prune (IPv6) command in the PIM-IPv6 view. By default, if the pim ipv6 holdtime join-prune command is not used, the value configured in the PIM view is used; otherwise, the value configured in the interface view is used.
