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:
Step

By default, multicast data cannot
be forwarded between
sub-VLANs that are associated
with a super VLAN.
4.
Clear all multicast
forwarding entries with the
super VLAN interface as the
incoming interface.
