• You can enable MLD snooping fast-leave processing either on the current port in interface view or
globally for all ports in MLD-snooping view. If configurations are made in both interface view and
MLD-snooping view, the configuration made in interface view takes priority.
To enable MLD snooping fast-leave processing globally:
Ste

Command Remarks
1. Enter system view.
system-view N/A
2. Enter MLD-snooping view.
mld-snooping N/A
3. Enable MLD snooping
fast-leave processing globally.
fast-leave [ vlan vlan-list ]
By default, MLD snooping
fast-leave processing is disabled.
To enable MLD snooping fast-leave processing on a port:
Ste

Command Remarks
1. Enter system view.

N/A
3. Enable MLD snooping
fast-leave processing on the
port.
mld-snooping fast-leave [ vlan
vlan-list ]
By default, MLD snooping
fast-leave processing is disabled.
Disabling a port from becoming a dynamic router port
The following problems might exist in a multicast access network:
• After receiving an MLD general query or IPv6 PIM hello message from a connected host, a router
port becomes a dynamic router port. Before its timer expires, this dynamic router port receives all
multicast packets within the VLAN that the port belongs to and forwards them to the host. This
affects normal multicast reception of the host.
• In addition, the MLD general query and IPv6 PIM hello message that the host sends affect the
multicast routing protocol state on Layer 3 devices, such as the MLD querier or DR election. This
might further cause network interruption.
To solve these problems and to improve network security and the control over multicast users, you can
disable the router port from becoming a dynamic router port.
To disable a port from becoming a dynamic router port:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter Layer 2 Ethernet
interface view.
interface interface-type interface-number N/A
3. Disable the port from
becoming a dynamic router
port.
mld-snooping router-port-deny [ vlan
vlan-list ]
By default, a port can
become a dynamic router
port.
This configuration does not
affect the static router port
configuration.
