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, affecting
normal multicast reception of the host.
In addition, the MLD general query and IPv6 PIM hello message that the host sends affects the
•
multicast routing protocol state on Layer 3 devices, such as the MLD querier or DR election, and
might further cause network interruption.
To solve these problems, you can disable the router port from becoming a dynamic router port after the
port receives an MLD general query or IPv6 PIM hello message, so as to enhance network security and
the control over multicast users.
