Configuring Basic Functions of IGMP
Configuration Prerequisites
Before configuring the basic functions of IGMP, complete the following tasks:
•
Configure any unicast routing protocol so that all devices in the domain are interoperable at the
network layer.
•
Configure PIM-DM or PIM-SM
Before configuring the basic functions of IGMP, prepare the following data:
•
IGMP version
•
Multicast group and multicast source addresses for static group member configuration
•
ACL rule for multicast group filtering
•
The maximum number of multicast groups that an interface can joined
