Introduction

This document provides configuration examples of static multicast MAC address entries.

Prerequisites

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 multicast MAC addresses.

Example: Configuring static multicast MAC address entries

Network configuration

As shown in Figure 1, Router A runs IGMP and acts as the IGMP querier. Switch A does not run a Layer 2 multicast protocol.

Configure Switch A so that only Host A and Host C can receive multicast data addressed to multicast group 224.1.1.1.

Figure 1 Network diagram

 

Analysis

Multicast MAC address entries guide Layer 2 multicast forwarding. They can be dynamically created through Layer 2 multicast protocols or manually configured by binding multicast MAC addresses and ports.

In this example, Switch A does not run a Layer 2 multicast protocol. To control destination ports of Layer 2 multicast data, configure a static multicast MAC address entry on Switch A.

Restrictions and guidelines

The manually configured multicast MAC address in the multicast MAC address entry must be unused.

Procedures

# On Switch A, create VLAN 100.

<SwitchA> system-view

[SwitchA] vlan 100

[SwitchA-vlan100] quit

# Configure Ten-GigabitEthernet 1/0/1 through Ten-GigabitEthernet 1/0/4 to operate in Layer 2 mode, and assign the ports to VLAN 100.

[SwitchA] interface range ten-gigabitethernet 1/0/1 to ten-gigabitethernet 1/0/4

[SwitchA-if-range] port link-mode bridge

[SwitchA-if-range] port access vlan 100

[SwitchA-if-range] quit

# Translate multicast IP address 224.1.1.1 to a multicast MAC address (0100-5e01-0101). (Details not shown.)

# Create a static entry for multicast MAC address 0100-5e01-0101 with Ten-GigabitEthernet 1/0/2 and Ten-GigabitEthernet 1/0/4 in VLAN 100 as outgoing ports.

[SwitchA] mac-address multicast 0100-5e01-0101 interface ten-gigabitethernet 1/0/2 ten-gigabitethernet 1/0/4 vlan 100

Verifying the configuration

# Display static multicast MAC address entries in VLAN 100 on Switch A.

[SwitchA] display mac-address multicast vlan 100

MAC Address      VLAN ID    State            Port/NickName            Aging

0100-5e01-0101   100        Multicast        XGE1/0/2                 N

                                             XGE1/0/4

The output shows that Ten-GigabitEthernet 1/0/2 and Ten-GigabitEthernet 1/0/4 have become outgoing ports of multicast MAC group 0100-5e01-0101.
