Multicast Per VLAN

I have a network like below. My L3 distribution switch routing all access switch Vlans 518 and 718. My L3 and Core switch is connected with Access 4094. I have several video cameras in each L2 switch. My Host is connected with core switch vlan and source cameras are connected in L2 switch vlans. I have configured Manual RP in to the core switch and used PIM in Access mode 4094 to discover other L3 switch. I have configured PIM on source vlan 718 and 518 and host vlans 102. I have one multicast group 232.192.30.100 and all L3 switch have static RP address pointed. I have having issue getting multicast traffic from source. I have unicast traffic without any issue. When I ping multicast group, i got sometimes source camera valn gateway responding but not the multicast cameras. All cameras are configured with multicast ip address and camera is valid for multicast. Please need advice what I need to do in this situation.

Hi MD,

On each L3 device (router and L3 switches) you need to configure the static RP address, sounds like you did that. You also need to enable PIM on all L3 interfaces. You did that for VLAN 102, 518, 718 so that sounds correct.

IGMP snooping is enabled on your L2 switches?

When you send a ping from the source to 232.192.30.100. What do you see with show ip mroute? Which L3 devices forward your multicast traffic and which doesn’t?

** I have 3 video cameras on this 718 VLAN and none of them are responding but i got Ping response from source 10.129.167.203 is not a member of 718 Vlan. I think the problem with multicast grouping. How can I add the source video cameras into the group 232.192.30.100?
Please advice. When I use show ip igmp membership i can see others groups are associated with the vlan but not the one I am requesting the group member 232.192.30.100
