Hi list, I have set up 2 routers with FreeBSD 6.0-RELEASE. They are using carp interfaces, so one is a master router and another is a backup. They seemed to work fine, but a few days later I noticed that not only master router but also backup router replies to arp-requests of the common IP address from a layer 3 switch. This behavior confuses the switch, and sometimes it makes the switch to send a packet addressed to the common IP address to the port which is connected to backup router. I googled and found that OpenBSD fixed this problem in ip_carp.c 1.62. I hope that someone import this into FreeBSD... -------------------- Kazuaki Oda
