Hello I want to learn something about multicast routing. First I had setuped IGMP proxy in GNS3 ICMP on address 224.2.3.4 that worked and I turned into real mikrotik device. I have lab rb951g-2hnd and I setuped IGMP proxy on that still ICMP works but when I start stream via VLC to 224.2.3.4 udp 1234 that dont work packets arent be forwarded to another ether. Next i setuped PIM-SM and my grup address is in UIB S and UIB SG but when client device are sending IGMP join group nothing is happening. What can cause these ? I tested with address 239.0.50.50 and still nothing. I dont have any configuration only addreses on ether1 and ether2 + dhcp servers + igmp proxy or pim-sm nothing else. I dont post my configuration because these is only lab purpose I can setup everything from start.
Topic closed I dont setuped ttl on vlc server 
with ttl = 1 packets cant be routed.
