pim ipv6 dm

Function

The pim ipv6 dm command enables PIM-DM (IPv6) on an interface.

The undo pim ipv6 dm command restores the default configuration.

By default, PIM-DM (IPv6) is disabled on an interface.

Format

pim ipv6 dm

undo pim ipv6 dm

Parameters

None

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

PIM-DM (IPv6) is a multicast routing protocol in dense mode and applies to small-scale networks with densely-distributed group members.

After PIM-DM (IPv6) is enabled on an interface, the switch can set up the PIM neighbor relationship with the neighboring device. The switch then can process protocol packets received from PIM neighbors.

Prerequisites

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

Precautions

PIM-DM (IPv6) and PIM-SM (IPv6) cannot be enabled simultaneously on the device.

If PIM-DM (IPv6) and MLD need to be enabled on the same interface, enable PIM-DM (IPv6), and then enable MLD.

Running the pim ipv6 dm command failed on the VLANIF interface because Layer 2 multicast querier or report-suppress is enabled for this VLAN.

If both Layer 2 and Layer 3 multicast services are required in a VLAN, enable PIM (IPv6) on the corresponding VLANIF interface first, and then enable MLD snooping in the VLAN. If MLD snooping is enabled in the VLAN first, PIM (IPv6) cannot be enabled on the VLANIF interface.

Example

# Enable PIM-DM (IPv6) on VLANIF100.

<HUAWEI> system-view
[HUAWEI] multicast ipv6 routing-enable
[HUAWEI] interface vlanif 100
[HUAWEI-Vlanif100] pim ipv6 dm

# Enable PIM-DM (IPv6) on GE0/0/1.

<HUAWEI> system-view
[HUAWEI] multicast ipv6 routing-enable
[HUAWEI] interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1] undo portswitch
