<div>There are totally no IP ROUTING. Only MCAST ROUTING and L2 switching. Now I have added no icmp redirects. but as far as here are no IP routing traffic, there are no icmp redirect generates and no any CPU changes seen. Also I already have</div>
<div> no ip source-route</div>
<div>in the config<br></div>
<div>There are no RIP, no OSPF. only MBGP routing protocol.</div>
<div># egrep '^router' config</div>
<div>router dvmrp<br>router pim<br>router msdp<br>router pim<br>router bgp</div>

<div>in bgp router no any unicast active neighbors. only for address-family ipv4 multicast<br></div>
<div>we already have </div>
<div>ip multicast-perf </div>
<div>in our config for at list last year. (switch was rebooted after this command added)</div>
