8.2.5 Querier Config

In an IPv6 multicast network that runs MLD, a Layer 3 multicast device works as an MLD querier to
send out MLD queries and manage the multicast table. But MLD is not supported by the devices in
Layer 2 network. MLD Snooping Querier can act as an MLD Router in Layer 2 network. It can help
to create and maintain multicast forwarding table on the switch with the Query messages it
generates.
Specify the forbidden router ports which is mainly used to forbid
ports becoming router ports.
