timer join-prune (IPv6)

Function

The timer join-prune command configures the interval at which Join/Prune messages are sent to an upstream device.

The undo timer join-prune command restores the default interval.

By default, the interval at which Join/Prune messages are sent to an upstream device is 60 seconds.

Format

timer join-prune interval

undo timer join-prune

Parameters

Parameter	Description	Value
interval	Specifies the interval for sending Join/Prune messages.	The value is an integer that ranges from 1 to 18000, in seconds.

PIM-IPv6 view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

The switch sends join information to the upstream device, requesting the upstream device to forward multicast data. The switch sends prune information to the upstream device, requesting the upstream device to stop forwarding multicast data. Join information and prune information are encapsulated in Join/Prune messages. The PIM switch periodically sends Join/Prune messages to the upstream switch to update the forwarding status.

Prerequisites

IPv6 multicast routing has been enabled globally using the multicast ipv6 routing-enable command in the system view.

Precautions

This command is valid for both PIM-DM (IPv6) and PIM-SM (IPv6).

The interval configured using the timer join-prune command must be shorter than the interval configured using the holdtime join-prune (IPv6) command.

The timer join-prune command has the same function as the pim ipv6 timer join-prune command in the interface view. By default, if the pim ipv6 timer 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.

Example

# Set the interval at which Join/Prune messages are sent to 80s.

[HUAWEI] multicast ipv6 routing-enable
