I have a Cloud Router Switch 518-16XS-2XQ-RM with
RouterOS L5.
Environment: ST2110-30
Two devices connected into the router in one VLAN and in a second step in two different VLAN.
PTP is ok. Boundary Clocks works fine with correct MDB configuration but…
sometimes I am able to patch Multicast Signals and sometimes I’m not able to do it.
I tried with Layer 2 configuration with IGMP v2 and it doesn’t work properly.
I tried to elevate everything in Layer 3 with PIM-SM and it doesn’t work properly.
Strange things is everything should be fine in Torch and Packet Sniffer. Because I see the Udp Packet in transmission.
Is there anyone that can explain in a clear mode how to configure PIM-SM step by step?
I’m used to Cisco and FS and with Mikrotik everything sounds different and I need an help please
IGMP alone cannot work regardless of vendor implementation due to the use of VLANs. That introduces subnetting, thus L3. You absolutely require PIM-SM for this.¹ Show your configuration.
Because you are using a switch and not a router, you need 10G class speeds with hardware offload for full ST2110, minimum, even for 2k feeds.² Use iperf3 between the nodes to convince yourself that you have this minimum covered.
¹ …of the choices you list. There are other methods such as IGMP proxying, games with the switch chip rules, etc.
² …1080p60 = ~3 Gbit/sec. But, your -30 refers to the audio stream only, where you might be down in the 28 Mbit/sec range per channel for basic 48kHz/16 bit PCM, so 56 for stereo, etc.
It’s with PIM and it’s ST2110-30 Level A so 9.96 Mbps.
I have just 2 devices with 100Gb port and one with 1Gbps port
It’s just Mikrotik switch no other one.
Basically it must be working with IGMP snooping without any PIM, but here I got problem in both cases.
When I will come back Office I will show you the configuration
Thank you so much
Okay, so 48 kHz 24-bit PCM at 1.152 Mbit/sec per channel.
If you can’t get 10 Mbit/sec through this link, something is very wrong.
My bet? You haven’t set up the VLANs correctly, so you’ll get no unicast comms, either. Thus the iperf3 test. Get unicast working, and only then worry about multicast.
It could be I’m still using one bridge for every Vlan?
Bridging is something that going me confusing because it’s something different from other switch approach
I did in both cases, because my first try was within’ one Vlan and second try was with different Vlan architecture.
I suppose that is something that I Miss in the configuration because I have another Audio Mixer with a CRS3xx with Default Config (nothing applied but just as Mikrotik sent us)and Audio is subscribed.
