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 no ip source-route in the config There are no RIP, no OSPF. only MBGP routing protocol. # egrep '^router' config router dvmrp router pim router msdp router pim router bgp
in bgp router no any unicast active neighbors. only for address-family ipv4 multicast we already have ip multicast-perf in our config for at list last year. (switch was rebooted after this command added) Same as we already added mcast-hw-replic-oar ip multicast hardware-drop in config and it was reboted after such commands added. No any changes seen. Also I tried to add router pim + hardware-drop and no any changes seen. /Alexey 2009/3/12 Dimitar Kosadinov <[email protected]> > always use "no ip icmp redirect" !!! > this safe Your CPU :) > I dont sure Your multicast problem is this, but just use it.
