6.  Bind the interface with a VPN 
instance. 
ip binding vpn-instance

By default, an interface belongs to 
the public network, and is not 
bound with any VPN instance. 
7.  Enable IGMP. 
igmp enable  Disabled by default.

commands, see IP Routing Command Reference. 
Configuring IGMP versions  
Because the protocol packets of different IGMP versions vary in structure and type, you must configure the 
same IGMP version for all routers on the same subnet before IGMP can work properly.

Configuring static joining 
After an interface is configured as a static member of a multicast group or a multicast source group, it will 
act as a virtual member of the multicast group to receive multicast data addressed to that multicast group 
for the purpose of testing multicast data forwarding.  
Configuration guidelines 
•  Before you can configure an interface of a PIM-SM switch as a static member of a multicast group 
or a multicast source and group, if the interface is PIM-SM enabled, it must be a PIM-SM DR. If the 
interface is enabled with IGMP but not with PIM-SM, it must be an IGMP querier. For more 
information about PIM-SM and DR, see "Configuring PIM (available only on the S5500-EI)"
