[FreeBSD-9.0-RELEASE] CARP over bridge interface

F

Good day!

I have a problem with bringing up the carp0 interface over a bridge.

My system:
Code: 
[CMD]gate2# uname -a[/CMD]
FreeBSD gate2.2reallife.com 9.0-RELEASE FreeBSD 9.0-RELEASE #0: Tue Jan  3 07:46:30 UTC 2012     [email]root@farrell.cse.buffalo.edu[/email]:/usr/obj/usr/src/sys/GENERIC  amd64

ifconfig:
Code: 
[CMD]gate2# ifconfig bridge0[/CMD]
bridge0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
	ether 02:69:55:df:7b:00
	inet 192.168.0.2 netmask 0xffffff00 broadcast 192.168.0.255
	nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>

	        ifmaxaddr 0 port 1 priority 128 path cost 2000000 proto rstp
	        role root state forwarding
[CMD]gate2#[/CMD]

Adding the CARP interface:
Code: 
[CMD]gate2# ifconfig carp0 create[/CMD]
[CMD]gate2# ifconfig carp0 vhid 6 pass pass 192.168.0.3/24[/CMD]
[CMD]gate2# ifconfig carp0[/CMD]
carp0: flags=8<LOOPBACK> metric 0 mtu 1500
	inet 192.168.0.3 netmask 0xffffff00
	nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
	carp: INIT vhid 6 advbase 1 advskew 0
[CMD]gate2# ifconfig carp0 up[/CMD]
[CMD]gate2# ifconfig carp0[/CMD]
carp0: flags=9<UP,LOOPBACK> metric 0 mtu 1500
	inet 192.168.0.3 netmask 0xffffff00
	nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
	carp: INIT vhid 6 advbase 1 advskew 0
[CMD]gate2#[/CMD]

As you can see, carp0 is not running. And in /var/log/messages I see:
Code: 
Sep  2 21:54:10 gate2 kernel: bridge0: promiscuous mode enabled
Sep  2 21:54:10 gate2 kernel: ifa_del_loopback_route: deletion failed
Sep  2 21:54:10 gate2 kernel: ifa_add_loopback_route: insertion failed
Sep  2 21:54:41 gate2 kernel: in_scrubprefix: err=65, prefix delete failed
Sep  2 21:54:46 gate2 kernel: ifa_del_loopback_route: deletion failed
Sep  2 21:54:46 gate2 kernel: ifa_add_loopback_route: insertion failed

So the questions are:
  • Am I doing something wrong?
  • Is it real to bring up the CARP interface over the bridge?
Merci :)
 
Please upgrade to 9.1 or the release candidate for 9.2. FreeBSD 9.0 has been end-of-life for a while.

Sorry, I was wrong. The update doesn't help me. The carp interface now is up and running, but the kernel log shows me:
Code: 
gate kernel: bridge0: carp is not supported for this interface type
And at gate1 and gate2 the carp interface is the master. So if I ping a virtual address, two gates send me replies. :)

So, it doesn't work :(
