Disabling a port from becoming a dynamic router port
A receiver host might send MLD general queries or IPv6 PIM hello messages for testing purposes.
On the Layer 2 device, the port that receives either of the messages becomes a dynamic router port.
Before the aging timer for the port expires, the following problems might occur:
•
All IPv6 multicast data for the VLAN to which the port belongs flows to the port. Then, the port
forwards the data to attached receiver hosts. The receiver hosts will receive IPv6 multicast data
that it does not expect.
•
The port forwards the MLD general queries or IPv6 PIM hello messages to its upstream
multicast routers. These messages might affect the multicast routing protocol state (such as the
MLD querier or DR election) on the multicast routers. This might further cause network
interruption.
To solve these problems, you can disable the router port from becoming a dynamic router port when
receiving either of the messages. This also improves network security and the control over receiver
hosts.
To disable a port from becoming a dynamic router port:
