I got two ME3600X to connect the multicast servers with different multicast groups via on separated circuits. Expert I should receive the same multicast data from both circuits.
On last Thu, the secondary ME3600X suddenly stopped to receive the multicast packet. I tried to reload the box, but it doesn't help. By referring the interface status, IP multicasts didn't increase by comparing with the primary router. But the input rate is receiving data.
I'm wondering where were the multicast packets dropped. I tried to show the cpu-interface, can't find any stranger. Also checked with the upstearm provider, they confirmed the multicast data keep sending from their router.
