I have a problem where multicast packets are sent on ports where they should not.
The network contains five switches and no router, the five switches are connected in a circle and using RSTP. Among a lot of other devices there are a few devices connected to two switches (I have shown one in the drawing). These devices contains a two port switch which are not forwarding datapackets from one port to the other. My problem is that all multicast traffic on the network is being sent to these devices. The links to these devices are going through a slow speed modem so I don't want any extra traffic.
It is only nativ VLAN 1 used
The switches have all the same configuration except the line: ip igmp snooping querier, this line is only on the switch with address 10.1.10.54.
I do get the 239.192.1.36, 239.192.1.38, 239.192.1.39, 239.192.1.40, 239.192.1.41 and 239.192.1.42 on Fa 0/1-4
Anyone got an idea of why I get all multicast messages ut on Fa 0/4?
I'm using the the Native vlan 1 due to compability with the device I have connected.
