Multicast with IGMP snooping querier feature

[slandeira]

Hi,
I've configured the multicast in one vlan and it only works in one way, I've configured IGMP snooping on all switches trough wich multicast traffic goes from the multicast server to the receiver:

Server (172.30.7.137) <<>> SWBL3 <<>> SWTIC <<>> CPD_3 <<>> CPD_1 <<>> CPD_2 <<>> SWBL4 <<>> receiver (172.30.7.196)

Also, in one of the switches (CPD_1) I've configured the igmp snooping querier in vlan of Level 3 that the server and receiver belong to.

I've read that you only need to configure this two features to run the multicast at level 2, there is something else I should check?

Thanks in advance!

That is all you should need to do if you are only doing multicast within one vlan. Is it not working or are you just checking that you have done it correctly ?

hi,

I have seen in the intermediate switches that recognize the right igmp querier:
#show ip igmp snooping querier
Vlan IP Address IGMP Version Port
-------------------------------------------------- -----------
172.30.7.130 310 Po1 v3

but can not get the multicast in both directions, there is only a receiver and a transmitter and test software works only in a sense, what else could verify? what tests should be made?

thanks!

What exactly do you mean by "both ways".

Does the client receive the multicast stream from the server ?

Hi,

there is only one receiver and one transmitter, which must operate in both directions. We tested with an application and is found from a server it works but in reverse no. Multicast traffic only has to have in a sense? (in the sense server-> receiver?)

thanks!

Hi,

How about the line command:
ip igmp snooping querier mrouter interface (of the server)

in the interface vlan of level 3 for multicast traffic?

thanks!
