Configuring basic IGMP functions
Before you configure basic IGMP functions, complete the following tasks:
Configure any unicast routing protocol so that all devices are interoperable at the network layer.
Configure PIM.
Determine the IGMP version.
Determine the multicast group and multicast source addresses for static group member
configuration.
Determine the ACL for multicast group filtering.
Enabling IGMP
To configure IGMP, enable IGMP on the interface where the multicast group memberships are
established and maintained.
To enable IGMP:

4. Enable IGMP.
igmp enable Disabled by default.
Specifying the IGMP version
Because the protocol packets of different IGMP versions vary in structure and type, specify the same
IGMP version for all routers on the same subnet. Otherwise, IGMP cannot operate correctly.
