42.1.2 Adding/Deleting Static Multicast Address of VLAN
Hosts that do not support IGMP can receive corresponding multicast message by configuring the
static multicast address.
Perform the following configurations in global configuration mode:
Command Description
ip igmp-snooping
vlan
vlan_id
static
A.B.C.D
interface
intf
Adds static multicast address of VLAN.
no ip igmp-snooping vlan
vlan_id
static
A.B.C.D
interface
intf
Deletes static multicast address of VLAN.
42.1.3 Configuring Immediate-leave of VLAN
When the characteristic immediate-leave is configured, the switch can delete the port from the port list of the
multicast group after the switch receives the leave message. The switch, therefore, does not need to enable
the timer to wait for other hosts to join the multicast. If other hosts in the same port belongs to the same group
and their users do not want to leave the group, the multicast communication of these users may be affected.
In this case, the immediate-leave function should not be enabled.
Perform the following configurations in global configuration mode:
Command Description
ip igmp-snooping vlan
vlan_id
immediate-leave
Configures the
immediate-leave
function of
the VLAN.
no ip igmp-snooping vlan
vlan_id
immediate-leave
Sets immediate-leave of VLAN to its default
value.
The immediate-leave characteristic of VLAN is disabled by default.
42.1.4 Configuring Static Routing Interface of VLAN
Configure the static routing interface and send the multicast packet to the routing port. The switch will send
the multicast report packets to all routing ports in vlan.
Run following commands in the global configuration mode:
Command Purpose
ip igmp-snooping
vlan
vlan_id
mrouter
interface
intf
Add the static routing port of VLAN.
no ip igmp-snooping vlan
vlan_id
mrouter
interface
intf
Delete the static routing port of VLAN.
42.1.5 Configuring IPACL of Generating Multicast Forward Table
