Configuring a Port as a Simulated Group Member
Simulated joining in IGMP Snooping is implemented in the same way as in IGMP except that IGMP
Snooping establishes and maintains IGMP Snooping entries.

The port to be configured must belong to the specified VLAN; otherwise the configuration does not
take effect.

You can use the source-ip source-address command to specify a multicast source address that the
port will join as a simulated host. This configuration takes effect when IGMPv3 Snooping is enabled
in the VLAN.
