Usage guidelines

You must enable the IGMP snooping feature and enable IGMP snooping for a VLAN before you enable PIM snooping for the VLAN.

PIM snooping does not take effect on sub-VLANs of a multicast VLAN.

Examples

# Enable the IGMP snooping feature, and then enable IGMP snooping and PIM snooping for VLAN 2.

<Sysname> system-view

[Sysname] igmp-snooping

[Sysname-igmp-snooping] quit

[Sysname] vlan 2

[Sysname-vlan2] igmp-snooping enable

[Sysname-vlan2] pim-snooping enable
