Hi all,
I need to transfer a multicast stream from one point to another of our network.
There are three RB1000, let’s call them A, B, C. We have a radio L2 link between A and B and a mixed fiber/radio L2 link between B and C. B routes the traffic from A to C.
A and C are the two endpoints: the stream enters on an ethernet on A end exits on and ethernet on C. An EoIP tunnel is configured between A and C, which is bridged with the physical interfaces on each router.
The issue is the following: hen we test the tunnel with the multicast stream, we record ~24 Mbps at the source port but only ~20 Mbps at the destination port.
Do you have any hint on why this may be happening and how to troubleshoot this? Are there better/optimal configuration we could try to achieve the same goal?
Thank you in advance.
P.S.: I forgot to mention that a bandwidth test between the two endpoints doesn’t show any issue.
Are you sure that the 24 Mbps on the source port is all traffic that you would expect to get to the destination port? If you know the source of the stream I suggest checking on the actual multicast traffic entering the source port from that specific multicast source of interest.
Thank you for the answer. I don’t have much experience with multicast and I’m not sure I’m understanding your suggestion. Just to add a couple of details, there is only one source and it’s connected to the ethernet on the first RB1000 and that’s the only source of traffic going through the tunnel. With this config source device should see just a L2 link which goes directly to the destination port, so I don’t see any reason why the some traffic wouldn’t exit. Or am I wrong on something?
It certainly sounds as if the traffic should all appear at the destination.
Where did you get the 20/24 Mbps figures from? Are these from the interfaces (i.e. totals) or are you looking at Torch on the interfaces so you would see any breakdown per source/target?
