MLD snooping configuration example
Network requirements
As shown in
:
•
The network is a Layer 2-only network.
•
Host A and Host B are receivers of IPv6 multicast group FF1E::101.
•
All host receivers run MLDv1, and all switches run MLDv1 snooping. Switch A (which is close to
the multicast source) acts as the MLD querier.
To prevent the switches from flooding unknown packets in the VLAN, enable all the switch to drop
unknown IPv6 multicast packets.
