Configuration procedure

Assign an IP address and subnet mask to each interface according to Figure 22. (Details not shown.)

Configure OSPF on the PIM network to make sure the following conditions are met: (Details not shown.)

• The switches are interoperable at the network layer.

• The switches can update their routing information.

Enable IP multicast routing, and enable IGMP and PIM-DM:

# On Switch A, enable IP multicast routing.

<SwitchA> system-view
[SwitchA] multicast routing
[SwitchA-mrib] quit

# Enable IGMP on the receiver-side interface (VLAN-interface 100).

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

# Enable PIM-DM on VLAN-interface 101.

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

# On Switch B, enable IP multicast routing.

<SwitchB> system-view
[SwitchB] multicast routing
[SwitchB-mrib] quit

# Enable IGMP on the receiver-side interface (VLAN-interface 200).

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

# Enable PIM-DM on VLAN-interface 201.

[SwitchB] interface vlan-interface 201
[SwitchB-Vlan-interface201] pim dm
[SwitchB-Vlan-interface201] quit

# On Switch C, enable IP multicast routing.

<SwitchC> system-view
[SwitchC] multicast routing
[SwitchC-mrib] quit

# Enable IGMP on the receiver-side interface (VLAN-interface 200).

[SwitchC] interface vlan-interface 200
[SwitchC-Vlan-interface200] igmp enable
[SwitchC-Vlan-interface200] quit

# Enable PIM-DM on VLAN-interface 202.

[SwitchC] interface vlan-interface 202
[SwitchC-Vlan-interface202] pim dm
[SwitchC-Vlan-interface202] quit

Configure a multicast group policy on Switch A so that the hosts connected to VLAN-interface 100 can join only multicast group 224.1.1.1.

[SwitchA] acl number 2001
[SwitchA-acl-basic-2001] rule permit source 224.1.1.1 0
[SwitchA-acl-basic-2001] quit
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] igmp group-policy 2001
[SwitchA-Vlan-interface100] quit
