Example for Configuring Static Multicast MAC Addresses

Networking Requirements

As shown in Figure 1, the router connects to a user network through the switch. There are three receivers on the network: HostA, HostB, and HostC. HostA and HostC are allowed to receive packets with destination address 0x0100-5A0A-0A0A, but HostB is not.

Configuration Roadmap

To meet the preceding requirement, configure static multicast MAC addresses on the Layer 2 switch. The configuration roadmap is as follows:

Create a VLAN and add interfaces to the VLAN.
Configure the static multicast MAC address 0x0100-5A0A-0A0A on GE0/0/1 and GE0/0/2.

Procedure

Create a VLAN and add interfaces to the VLAN.

[Switch-GigabitEthernet0/0/3] port hybrid untagged vlan 10
[Switch-GigabitEthernet0/0/3] quit
[Switch] interface gigabitethernet 0/0/4
[Switch-GigabitEthernet0/0/4] port link-type hybrid
[Switch-GigabitEthernet0/0/4] port hybrid pvid vlan 10
[Switch-GigabitEthernet0/0/4] port hybrid untagged vlan 10
[Switch-GigabitEthernet0/0/4] quit

Configure the static multicast MAC address on the interfaces connected to HostA and HostC.

[Switch] interface gigabitethernet 0/0/1
[Switch-GigabitEthernet0/0/1] mac-address multicast 0100-5a0a-0a0a vlan 10
[Switch-GigabitEthernet0/0/1] quit
[Switch] interface gigabitethernet 0/0/2
[Switch-GigabitEthernet0/0/2] mac-address multicast 0100-5a0a-0a0a vlan 10
[Switch-GigabitEthernet0/0/2] quit

Verify the configuration.
