pim ipv6 timer graft-retry

Function

The pim ipv6 timer graft-retry command sets the interval for retransmitting Graft messages on an interface.

The undo pim ipv6 timer graft-retry command restores the default value of the interval.

By default, the interval for retransmitting Graft messages on an interface is 3 seconds.

Format

pim ipv6 timer graft-retry interval

undo pim ipv6 timer graft-retry

Parameters

Parameter	Description	Value
interval	Specifies the interval of retransmitting Graft messages.	The value is an integer that ranges from 1 to 65535, in seconds.

Views

GE interface view, XGE interface view, MultiGE interface view, 25GE interface view, 40GE interface view, 100GE interface view, Eth-Trunk interface view, VLANIF interface view, loopback interface view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

In PIM-DM (IPv6) mode, when a member joins a pruned group, the switch sends a Graft message and waits to receive an ACK message from the upstream switch. If the downstream switch does not receive the ACK message in the period configured through the command, the switch resends the Graft message until the switch receives the ACK message from the upstream switch.

Prerequisites

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

Precautions

This command is valid for only PIM-DM (IPv6).

Example

# Set the interval for retransmitting Graft messages to 80s on VLANIF100.

[HUAWEI] interface vlanif 100
[HUAWEI-Vlanif100] pim ipv6 timer graft-retry 80

# Set the interval for retransmitting Graft messages to 80s on GE0/0/1.
