VOSS Multicast across vlans, mvpn and IP Shortcuts multicast

[XTRMUser]

Running VOSS 8.10. 

Stream goes through our router (VOSS), so the vlans have IP address on the switch/router. The path takes the stream to another VOSS switch, with no IP address on the vlan. So, theoretically, I should use "mvpn-isid 0" (to use the GRT). Then of course, in both cases, I need the "ip spb-multicast-enable".

Is the above correct? Also noting that in "router isis, spbm 1 multicast enable" is set up on both VOSS switches.

If I need to use a querier address, should I use routed querier  "ip igmp routed-spb-querier-addr <IP address>" or the regular "ip igmp snoop-querier-addr <ip address>"? I've seen examples with both, so I'm a bit confused.

Thanks for any clarification, and help.

Hi,

If I understand you correctly, you have different L3 networks and clients on these networks that should connect to the same multicast sender on one of these L3 networks?
In this case you need to enable spbm 1 multicast enable on the isis router. You will also need to configure ip spbm-multicast enable for all L3 VLANs that are to participate in the multicast stream.
There is no need to configure the igmp-snooping querier, the spbm switches are automatically assigned as the querier if igmp-snooping is enabled on that interface, you can set it to specify exactly which spbm switch should be the querier.

Best regards,
Phil
