It has been quite sometime since I have configured a multicast network. Yesterday I tried configuring it on the Production environment but didn't work. We have the multicast servers connected directly to the Core Switch (x2) and I can see the switch is receiving multicast packets but it is not forwarding to the ASA firewall. We have many more devices after the ASA but I am stuck on the first two devices. Can someone help to see what is missing from the config below?
