Hi, I reported a problem a few days ago that CARP backup host replies ARP request. This problem has been fixed, thanks. But I found one more problem. 1) master host and backup host are connected to the same layer 3 switch. 2) at master host, I run the following command: # ifconfig carp2 create # ifconfig carp2 vhid 22 advskew 10 pass xxxx 192.168.1.7/24 3) master host sends gratuitous ARP. 4) at backup host, I run the following command: # ifconfig carp2 create # ifconfig carp2 vhid 22 advskew 100 pass xxxx 192.168.1.7/24 5) backup host sends gratuitous ARP. And so, layer 3 switch sends packets addressed for 192.168.1.7 to the port connected to backup host, sigh... I don't know how to fix it. Is there any reason why CARP backup host sends gratuitous ARP? -------------------- Kazuaki Oda
