2.3 RIGMP Querier
The join and leave multicast group messages belongs to the IGMP protocol. Most switches have a timeout
at the multicast group table. The timeout can be named “ Host timeout ” or “ Aging timeout ”.
At the timeout the multicast group is cleared and multicasting stops.
To avoid this the following can be done:
•
Increase “Host timeout”/“Aging timeout” value.
•
Configure the multicasting manually at the switch.
•
Install an IGMP Querier in the network.
•
Use the internal IGMP Querier of the switch (if the switch supports this).
