The following information provides an example for configuring Layer 2 IPv6 multicast.


This document applies to Comware 7-based access points. Procedures and information in the examples might be slightly different depending on the software or hardware version of the access points.

The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

This document assumes that you have basic knowledge of Layer 2 multicast.

Example: Configuring Layer 2 IPv6 multicast

Network configuration

As shown in Figure 1:

·     The source sends IPv6 multicast traffic to IPv6 multicast group FF1E::1.

·     The client is a receiver host of the IPv6 multicast group.

·     The source and the client can reach each other.

Configure Layer 2 IPv6 multicast on the fat AP so that the client can receive the IPv6 multicast traffic from the source.

Figure 1 Network diagram



To implement Layer 2 IPv6 multicast, enable MLD snooping globally and in the VLAN to which the client belongs.

Restrictions and guidelines

Make sure the devices on the network can reach each other.


Configuring the router

# Enable IP multicast routing.

<RouterA> system-view

[RouterA] ipv6 multicast routing

[RouterA-mrib] quit

# Enable IPv6 PIM-DM on GigabitEthernet 1/0/1.

[RouterA] interface gigabitethernet 1/0/1

[RouterA-GigabitEthernet1/0/1] pim ipv6 dm

[RouterA-GigabitEthernet1/0/1] quit

# Enable MLD on GigabitEthernet 1/0/2.

[RouterA] interface gigabitethernet 1/0/2

[RouterA-GigabitEthernet1/0/2] mld enable

[RouterA-GigabitEthernet1/0/2] quit

Configuring the fat AP

1.     Configure wireless services:

# Create VLAN 100.

<AP> system-view

[AP] Vlan 100

[AP-vlan100] quit

# Create service template service1 and enter its view.

[AP] wlan service-template 1

# Configure the SSID as service.

[AP-wlan-st-1] ssid service

# Specify VLAN 100 for clients to access the WLAN defined by the service template.

[AP-wlan-st-1] vlan 100

# Enable the service template.

[AP-wlan-st-1] service-template enable

[AP-wlan-st-1] quit

# Bind the service template to interface WLAN-Radio 1/0/1.

[AP] interface WLAN-Radio 1/0/1

[AP-WLAN-Radio1/0/1] service-template 1

[AP-WLAN-Radio1/0/1] quit

2.     Configure MLD snooping:

# Enable MLD snooping globally.

[AP] mld-snooping

[AP-mld-snooping] quit

# Enable MLD snooping on VLAN 100.

[AP] vlan 100

[AP-vlan100] mld-snooping enable

[AP-vlan100] quit

3.     Configure GigabitEthernet 1/0/1 on the AP as a trunk port, and assign the port to VLAN 100.

[AP] interface GigabitEthernet 1/0/1

[AP-GigabitEthernet1/0/1] port link-type trunk

[AP-GigabitEthernet1/0/1] port trunk permit vlan 100

[AP-GigabitEthernet1/0/1] quit

4.     Configure the client to access the WLAN service with the SSID service and request multicast traffic for IPv6 multicast group FF1E::1. (Details not shown.)

Verifying the configuration

# Display detailed information about dynamic MLD snooping group entries for VLAN 100 on the AP.

[AP]display mld-snooping group vlan 100 verbose

Total 1 entries.


VLAN 100: Total 1 entries.


    Attribute: local port

    FSM information: normal

    Host slots (0 in total):

    Host ports (1 in total):

      WLAN-BSS1/0/20                        (00:03:23)

The output shows that WLAN-BSS 1/0/20 on the AP has joined the IPv6 multicast group FF1E::1.
