H3C S5500-EI - Configuring Basic IGMP Functions; Enabling IGMP

109
• If a feature is not configured on an interface in interface view, the global configuration in IGMP
view will apply to that interface. If a feature is configured in both IGMP view and interface view, the
configuration in interface view will be given priority.
Configuring basic IGMP functions
Before you configure basic IGMP functions, 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.
• Determine the IGMP version.
• Determine the multicast group and multicast source addresses for static group member
configuration.
• Determine the ACL rule for multicast group filtering.
• Determine the maximum number of multicast groups that an interface can join.
Enabling IGMP
To configure IGMP, you must enable IGMP on the interface for which the multicast group memberships
will be established and maintained.
