    Configuring Hardware Multicast Packet Replication

    The following topics explain how to configure hardware multicast packet replication without and with OIF-mapping:

    Configuring Hardware Multicast Packet Replication Without OIF-Mapping

    To configure hardware multicast packet replication without OIF-mapping:

    1. Configure port 8 on a high-density Ethernet module to accept redirected egress multicast traffic.
      1. Specify the Gigabit Ethernet interface on port 8.
      2. Create a VLAN major interface.
      3. Create a VLAN subinterface.
      4. Assign a VLAN ID.
      5. Configure an unnumbered IP interface.
      6. Enable IGMP on the interface with only multicast-data-forwarding capability.
        host1(config)#interface gigabitEthernet 2/8 host1(config-if)#encapsulation vlan host1(config-if)#interface gigabitEthernet 2/8.1 host1(config-if)#vlan id 1 host1(config-if)#ip unnumbered loopback 0 host1(config-if)#ip igmp version passive
    2. Configure an IP interface to redirect egress multicast traffic to port 8.
      1. Create a VLAN subinterface.
      2. Assign a VLAN ID.
      3. Assign an IP address.
      4. Configure the interface to redirect egress multicast traffic to port 8.
        host1(config)#interface gigabitEthernet 2/0.101 host1(config-if)#vlan id 1 host1(config-if)#ip address 10.1.1.1 255.255.255.0 host1(config-if)#ip multicast ioa-packet-replication gigabitEthernet 2/8.1

    Configuring Hardware Multicast Packet Replication With OIF-Mapping

    This section describes how to configure hardware multicast packet replication with OIF-mapping.

    1. Configure port 8 on a supported high-density Ethernet module to accept redirected egress multicast traffic. For information about supported high-density Ethernet modules see Hardware Multicast Packet Replication Overview.
    2. Use OIF maps to map the subscriber IGMP interfaces (C-VLANs) to the dedicated multicast VLAN (M-VLAN). The dedicated M-VLAN should be located on the line module containing the IOA replication interface. The C-VLAN and M-VLAN can either be on the same or different line modules.
    3. Configure the dedicated M-VLAN to redirect egress multicast traffic to port 8.
