I suggest to block also icmp packets towards 224/4. Ping with destination
within multicast range is overloading IGMP snooping processes on our
switches, even on Catalyst 6500s.

Folks, please filter TCP packets destined to 224/4. TCP can't do
multicast, and that should help reduce the MSDP load caused by Sasser.
Thanks.
