1352 CHAPTER 88: IGMP CONFIGURATION COMMANDS

By default, no multicast group filter is configured, namely a host can join any multicast group.

n When you use an advanced ACL as a filter, the source address in the ACL rule is the address of the multicast source specified in the IGMPv3 reports, rather than the source address in the IP packets.

Example # Configure an ACL rule so that hosts on the subnet attached to Ethernet 1/0 can join multicast group 225.1.1.1 only.

<Sysname> system-view [Sysname] acl number 2005

[Sysname-acl-basic-2005] rule permit source 225.1.1.1 0

[Sysname-acl-basic-2005] quit [Sysname] interface ethernet 1/0 [Sysname-Ethernet1/0] igmp group-policy 2005
