[f-nsp] Multicast causing high CPU

[Dimitar Kosadinov]

always use "no ip icmp redirect" !!!
this safe Your CPU :)
I dont sure Your multicast problem is this, but just use it. This reflect to OLD RIPv1 based routing only, I sure you dont use rip.
try use "ip multicast-perf"  too / need reload btw to see changes /
sorry for my bad english
