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
