Sorry to duplicate, but I had sent this from the wrong address.
Hopefully I will get all the responses from this one.
I have to 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<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500

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
If I down the carp1 interface on either box the other box becomes
master. If I down the carp0 interface on either box, the other stays
backup. Both carp0 interfaces stay backup all the time and therefore I
can't access 192.168.1.10.
The questions has been asked, do I see the the multicast traffic, and
are their firewall rules that could be blocking it?
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.
Thanks,
Chris
