Source Specific Multicast (SSM)

Does anyone know how to configure Source specific Multicast (SSM) on a cisco  switch?

[Joseph W. Doherty]

On a L3 switch, correct?

Hello Robert,

Enable multicast routing (global)
ip multicast-routing [distributed]

Enable SSM on all routers. If you do not specify a group, then the 232.0.0.0/8 range will be used.
ip pim ssm [default|range]

Enable PIM Sparse at interface level
ip pim sparse-mode

Enable IGMPv3 on the source and receiver
ip igmp version 3
