Enabling multicast forwarding between
sub-VLANs of a super VLAN
A super VLAN is associated with multiple sub-VLANs. Sub-VLANs are isolated with each other at
Layer 2. For information about the super VLAN and sub-VLANs, see Layer 2—LAN Switching
Configuration Guide.
To enable multicast forwarding between sub-VLANs that are associated with a super VLAN:
1. Enter system view.
system-view
N/A
2. Enter VLAN interface view.
interface vlan-interface
interface-number
N/A
3. Enable multicast forwarding
between sub-VLANs that are
VLAN.

By default, multicast data cannot

4.
Clear all multicast
forwarding entries with the
super VLAN interface as the
incoming interface.
