If the switch receives a multicast packet and is still able to create new dynamic multicast
groups (upper limit not reached) and it has saved one or more ports via which it
received queries, the switch will
1. create a new multicast group for this multicast address, provided one does not
already exist and
2. add the port via which it received the multicast packet and all query ports to this new
group.
–
The multicast groups created as described above are deleted in accordance with the
timeout rules. For example, if no more membership reports are received, if the
associated port is deleted from the groups or if no port, other than the ports receiving
queries, is a member of the group, this group is deleted.
