Specifying 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. Otherwise, IGMP cannot work
properly.

Configuring an interface as a static member interface
To test the multicast data forwarding, you can configure an interface as a static member of a
multicast group or a multicast source and group. Then, the interface can receive multicast data
addressed to that multicast group.
Configuration guidelines
•
When you configure an interface of a PIM-SM device as a static member interface:
{
If the interface is enabled with PIM-SM, it must be a PIM-SM DR.
{
If the interface is enabled with IGMP instead of PIM-SM, it must be an IGMP querier. For
more information about PIM-SM and a DR, see "
."
•
A static member interface does not respond to queries that the IGMP querier sends. When you
configure an interface as a static member or cancel this configuration, the interface does not
unsolicitedly send any IGMP report or IGMP leave message. In other words, the interface is not
a real member of the multicast group or the multicast source and group.
