Example: Configuring MLD proxying

Network configuration

As shown in Figure 105:

Configure the MLD proxying feature on Switch B so that Switch B can maintain group memberships and forward IPv6 multicast traffic without running IPv6 PIM-DM.

Figure 105: Network diagram

Procedure

  1. Assign an IPv6 address and prefix length to each interface, as shown in Figure 105. (Details not shown.)

  2. Enable IPv6 multicast routing, IPv6 PIM-DM, MLD, and MLD proxying:

    # On Switch A, enable IPv6 multicast routing.

    <SwitchA> system-view
    [SwitchA] ipv6 multicast routing
    [SwitchA-mrib6] quit
    

    # Enable IPv6 PIM-DM on VLAN-interface 101.

    [SwitchA] interface vlan-interface 101
    [SwitchA-Vlan-interface101] ipv6 pim dm
    [SwitchA-Vlan-interface101] quit
    

    # Enable MLD on VLAN-interface 100.

    [SwitchA] interface vlan-interface 100
    [SwitchA-Vlan-interface100] mld enable
    [SwitchA-Vlan-interface100] quit
    

    # On Switch B, enable IPv6 multicast routing.

    <SwitchB> system-view
    [SwitchB] multicast ipv6 routing-enable
    [SwitchB-mrib6] quit
    

    # Enable MLD proxying on VLAN-interface 100.

    [SwitchB] interface vlan-interface 100
    [SwitchB-Vlan-interface100] mld proxying enable
    [SwitchB-Vlan-interface100] quit
    

    # Enable MLD on VLAN-interface 200.

    [SwitchB] interface vlan-interface 200
    [SwitchB-Vlan-interface200] mld enable
    [SwitchB-Vlan-interface200] quit
    

Verifying the configuration

# Display IPv6 multicast group membership information maintained by the MLD proxy on Switch B.

[SwitchB] display mld proxy group
MLD proxy group records in total: 1
