4.9 MLD Snooping Configuration
MLD Snooping Overview
Corresponding to the IGMP protocol, MLD is a multicast management protocol in IPv6
environment. MLD v1/v2 is supported.
It is impossible to use a multicast address as a source address in a packet, so a switch
cannot learn the multicast address.
When receiving a multicast message, a switch
broadcasts the message on all ports in the same VLAN. If no measures are not taken,
unwanted multicast messages may be spread to each node of the network, causing a
great waste of network bandwidth resource.
Multicast Listener Discovery (
MLD
) snooping monitors MLD protocol communication
between a host and a router. In this way, a multicast message is sent to the ports in the
multicast forwarding table instead of all ports. This limits multicast message spread on
LAN switches, reduces network bandwidth waste, and enhances switch usage.
Configuring MLD Snooping
The MLD snooping configuration includes the following commands:
Command
Function
zte(cfg)#
set mld snooping
{
enable
|
disable
}
Enables or disables the MLD snooping
function globally.
zte(cfg)#
set mld snooping
{
add
|
delete
}
vlan
<
vlanlist
>
Adds or deletes an MLD snooping
VLAN.
zte(cfg)#
set mld snooping add maxnum
<
1-256
>
vlan
<
vlanlist
>
Sets the maximum number of multicast
groups of a specific VLAN.
zte(cfg)#
set mld snooping vlan
<
1-4094
>
add group
<
ipv6-address
>
port
<
portlist
>
Adds a static group to a specific VLAN
and adds a port to the static group.
zte(cfg)#
set mld snooping vlan
<
1-4094
>
delete group
<
ipv6-address
>[
port
<
portlist
>]
Clears static groups in a specific VLAN
and clears the ports in the static groups.
zte(cfg)#
set mld snooping vlan
<
1-4094
>{
add
|
delete
}
mrouter port
<
port-id
>
Adds or clears a routing ports in a
specific VLAN.
zte(cfg)#
set mld snooping
{
host-time-out
|
mrouter-time-out
}<
30-65535
>
Sets the time-out period between the
router port and the host port.
zte(cfg)#
set mld snooping query-interval
<
30-65535
>
Sets the interval for sending query
packets.
