IPTV Multicast over VLAN via Switch

Hi,
I will bring multicast SPTS IPTV from multicast Sender via vlan10 over CRS324 to an Router. On this Router i will bring vlan10 in vlan20 (on a bridge). Then Back again over the same CRS324 but to customers via vlan20.

Is this possible?

little pic:

CUSTOMER–vlan20----sfp0(with forwarding-override-to-sfp2)CRS324-sfp2–vlan10and20(separated)—Multicast-Router
multicast-sender—vlan10–sfp1(with forwarding-override-to-sfp2)|

Backgrund is, that my multicast-sender (streamer) is in my net, not in the room where Multicast-Router (controller) is.

Question is, the CRS324 works with same multicast-groups on vlan10 and vlan20 at the same time?!
Can handle the crs3xx the multicast with vlan?

I will use “forwarding-override” on the CRS to block all traffic from sustomer to streamer.

thank you
Christian
