>Description:
When I configure a sub interface with carp maually on two firewalls on a vlan both stays as master.
This results in an ip conflict in the network since both are active.
config fw1:
ifconfig lan0.10 create
ifconfig lan0.10 inet 10.50.189.254 netmask 255.255.255.0 vhid 12 pass iepheu5ZiafaM8Ba advbase 1 advskew 0 up
config fw2:
ifconfig lan0.10 create
ifconfig lan0.10 inet 10.50.189.254 netmask 255.255.255.0 vhid 12 pass iepheu5ZiafaM8Ba advbase 1 advskew 10 up
ifconfig fw1:
lan0.10: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=103<RXCSUM,TXCSUM,TSO4>
ether 00:25:90:97:98:53

ifconfig fw2:
