Last time I had a problem with performance on the router 7600 in our external network segment. On the one customer link there were a lot of multicast traffic and my router was broke down. It means that our BGP and
OSPF session were destroyed. When I looked for any reason in the syslog I found information something like this.
%MCAST-SP-6-IGMP_PKT_DROPPED: IGMP: IGMP Queue full (high packet rate/CPU busy), dropped 283112 packet(s) in last 5 minutes.
I don't why because I don't have enabled IGMP on the interfaces or multicast routing. Could you explain why
my router didn't drop this packet in ASIC but sent to the SP. What can I do to block this traffic in the future.
