Hmm, I can't seem to reproduce this. With just a static ARP like above and a flood ping of about 1000 pps the "show interface VlanX stats" doesn't show the "processor" part rising. At least not more than a single packet or two at most. ! C1#sh run part common | incl arp ! arp vrf SomeVRF 10.0.0.1 03bf.0a55.151e ARPA ! arp vrf SomeVRF 10.0.0.2 03bf.0a55.151d ARPA !
