Setup Multicast on Aruba Procurve 5400z

[Calle1748]

I need hosts on VLAN 20 to receive multicast packets from address 239.0.1.4 on VLAN 3.  This Procurve is the core router.  How would I make this configuration? 

I tried the following, but it did not work.

ip multicast-routing
vlan3
ip pim-sparse ip-addr any
vlan 20
ip pim-sparse ip-addr any

You need to add IP IGMP to each VLAN interface on the core switch

Would you please help me with the IGMP commands that i need to use to meet this configuration?
