I'm considering about the following network.
PC1-----L2SW------Router-----PC2
PC3------+
PC1:Multicast receiver
PC2:Multicast sender
I configured mulicast and igmp snooping on Router,L2SW.
In this situation,PC2 sends the multicast traffic of 234.1.2.3.
Router sends the igmp v2 membership query to 224.0.0.1 and PC1 replies by v2 membership report.
Only PC1 receives the multicast traffic of 234.1.2.3.
When PC1 sends the igmp v2 leave message to 224.0.0.2,the mulicast traffic of 234.1.2.3 does "NOT" streams to the L2SW at all except for the 224.0.0.1 of v2 membership query from Router once every 60 seconds(default). Is it right ?
If PC1 receives the multicast traffic of 234.1.2.3,I think that this is a following situation.
1)The connection between PC1 and L2SW was disconnected suddenly.That is to say,Router does not receive the igmp v2 leave message.This is 60 seconds at the maximum.(ip igmp query-interval:default 60seconds)
2)The interval until the mac address of multicast(234.1.2.3) will disappear.I'm not sure about the time to disappear.
Does this disappear soon after the router receives the igmp v2 leave message from PC1 ?
Then, I'm not sure about the meaning of ip igmp leave-timeout (default 120seconds).
Please let me know the meaning of this command.
Please confirm and let me know asap.
