R0106-HP MSR Router Series IP Multicast Command Reference(V7)

addresses in IGMP reports, respectively. The system determines that 0.0.0.0 is the multicast source

address for IGMPv1, IGMPv2, and IGMPv3 IS_EX and IGMPv3 TO_EX reports that do not carry any

multicast source addresses.

vlan vlan-list: Specifies a space-separated list of up to 10 VLAN items. Each item specifies a VLAN by its

ID or a range of VLANs in the form of start-vlan-id to end-vlan-id. The VLAN ID is in the range of 1 to

4094. If you do not specify any VLAN, the command takes effect on all VLANs.

Usage guidelines

If the specified ACL does not exist or the ACL rule is null, all multicast groups are filtered out.

You can configure different ACL rules on a port in different VLANs. However, for a given VLAN, a newly

configured ACL rule overrides the existing one.

This command is effective on the multicast groups that a port dynamically joins. If you configure the port

as a static member port for a multicast group, this command is not effective on the multicast group.

The configuration made in interface view is only effective on the current port and takes preference over

the global configuration.

Examples

# Apply ACL 2000 as a multicast group filter to VLAN 2 on GigabitEthernet 2/1/1 so that hosts

attached to the port can join only the multicast group 225.1.1.1.
