Carp master problem (sorry for the duplicate)

[Chris McGee]

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
         options=b<RXCSUM,TXCSUM,VLAN_MTU>
         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 <full-duplex>)
         status: active
em1: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
         options=b<RXCSUM,TXCSUM,VLAN_MTU>
         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 <full-duplex>)
         status: active
carp0: flags=41<UP,RUNNING> mtu 1500
         inet 192.168.1.10 netmask 0xffffff00
         carp: BACKUP vhid 1 advbase 1 advskew 0
carp1: flags=41<UP,RUNNING> mtu 1500
         inet 10.10.10.1 netmask 0xfffffff8
         carp: MASTER vhid 2 advbase 1 advskew 0

em0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
         options=b<RXCSUM,TXCSUM,VLAN_MTU>
         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 <full-duplex>)
         status: active
em1: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
         options=b<RXCSUM,TXCSUM,VLAN_MTU>
         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 <full-duplex>)
         status: active
carp0: flags=41<UP,RUNNING> mtu 1500
         inet 192.168.1.10 netmask 0xffffff00
         carp: BACKUP vhid 1 advbase 1 advskew 100
carp1: flags=41<UP,RUNNING> 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

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
