Hello Community, I have been scavenging the internet for possible leads or solutions but found nothing so far, wondering if someone has attempted this or maybe a similar network design or maybe some tips and tricks that might help with this configuration.
NOTE: I am using HSRP actually and from what I have read in the: https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9300/software/release/16-6/configuration_guide/ip_mcast_rtng/b_166_ip_mcast_rtng_9300_cg.pdf hsrp-aware PIM is not supported - but either way most of the equipment in the system is not PIM enabled which means I have to manually direct the MCAST stream, which is OK because the network is not very much complicated. Please see the simplified network layout attached.
So the idea here is that Server (on the left) with IP 10.10.40.50 is the source of the Multicast stream. I can see the MCAST traffic incoming on Physical Interface of the 9300 - the physical interface is linked to interface Vlan40 where I would be expecting the Multicast traffic to show up as well - I only see incoming unicast traffic at this point (the actual bitrate is reflecting the amount of MCAST traffic I am sending) which is not necessarily bad, but It does not look like this VLAN40 interface is considering this incoming traffic as Multicast at all, so that is issue #1, next step would be to get this traffic out of interface Vlan105 and into a PEP server (the server acts as a bridge of sorts, so anything going into it on subnet 192.168.15.0 /24 will be coming out on subnet 192.168.16.0 /24 after being processed). This traffic will then have to make it back to the 9300 on interface VLAN106 and from there the next hop would be the Modulator @ 192.168.254.111 IP address - this completes the actual path that actually Unicast and Multicast traffic will be traversing.
If anyone has any ideas please or has experienced the same situation trying to set up such a LAB
!
interface GigabitEthernet1/0/36
switchport trunk allowed vlan 40,100,103,203,303,4093

Here is where we see the output on the Physical Link:

NOW on a normal router if I would like to direct traffic out a certain interface I would use something like "ip igmp static-group [mcast group ip]" but this does not really help, and I am partially blaming the fact that interface Vlan40 does not understand that the incoming traffic is actual multicast ... any ideas are very much appreciated.
