I am hoping someone on this list has some insight for me. I have 2 machines in a test environment, the carp0 interface on the machines will not become master. The config is as follows: test1# ifconfig em0: flags=8943 mtu 1500 options=b inet 192.168.1.252 netmask 0xffffff00 broadcast 192.168.1.255 inet6 fe80::230:48ff:fe82:a77c%em0 prefixlen 64 scopeid 0x1 ether 00:30:48:82:a7:7c media: Ethernet autoselect (100baseTX ) status: active em1: flags=8943 mtu 1500 options=b inet 10.10.10.2 netmask 0xfffffff8 broadcast 10.10.10.7 inet6 fe80::230:48ff:fe82:a77d%em1 prefixlen 64 scopeid 0x2 ether 00:30:48:82:a7:7d media: Ethernet autoselect (100baseTX ) status: active carp0: flags=41 mtu 1500 inet 192.168.1.10 netmask 0xffffff00 carp: BACKUP vhid 1 advbase 1 advskew 0 carp1: flags=41 mtu 1500 inet 10.10.10.1 netmask 0xfffffff8 carp: MASTER vhid 2 advbase 1 advskew 0 em0: flags=8943 mtu 1500 options=b inet 192.168.1.253 netmask 0xffffff00 broadcast 192.168.1.255 inet6 fe80::230:48ff:fe80:21bc%em0 prefixlen 64 scopeid 0x1 ether 00:30:48:80:21:bc media: Ethernet autoselect (100baseTX ) status: active em1: flags=8943 mtu 1500 options=b inet 10.10.10.3 netmask 0xfffffff8 broadcast 10.10.10.7 inet6 fe80::230:48ff:fe80:21bd%em1 prefixlen 64 scopeid 0x2 ether 00:30:48:80:21:bd media: Ethernet autoselect (100baseTX ) status: active carp0: flags=41 mtu 1500 inet 192.168.1.10 netmask 0xffffff00 carp: BACKUP vhid 1 advbase 1 advskew 100 carp1: flags=41 mtu 1500 inet 10.10.10.1 netmask 0xfffffff8 carp: BACKUP vhid 2 advbase 1 advskew 100 both test1 and test2 have these sysctl variables: net.inet.carp.allow: 1 net.inet.carp.preempt: 1 net.inet.carp.log: 1 net.inet.carp.arpbalance: 0 The carp1 interface seems to operate properly. I can't get either box to become master for 192.168.1.10 If I do a tcpdump on the em0 interface on the boxes, I see multicast traffic out on em0 on test1 and I see multicast traffic from test1 on em0 of test2. The only firewall rules are pass in all and pass out all. On test1(should be the master): > netstat -ssp carp carp: 40572 packets received (IPv4) 326 discarded for bad vhid 160550 packets sent (IPv4) On test2(the backup); > netstat -ssp carp carp: 134298 packets received (IPv4) I'm hoping someone out here can help because this is driving me crazy and I can not even think about this for a production environment if I can't get it working in very simple test setup. Thanks, Chris
