Quagga adding routes via interface in FreenBSD

[S.I]

Hello, 
 As of quagga-0.99.3_2 zebra doesn't add static routes via interface on any
freebsd versions from 6-STABLE to FreeBSD 7.2-PRERELEASE #3: Wed Mar 25 11:38:45
EET 2009.
quagga-0.99.3 is working but everything after that version including 0.99.11 is
not working.

Here is the example:
#####################################################################################
zebra.conf
interface vlan11
ip route 10.10.0.0/16 vlan11
----------------------------
#ifconfig vlan11

vlan11: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
	options=3<RXCSUM,TXCSUM>
	ether 00:04:23:a7:60:48
	inet 172.16.16.1 netmask 0xffffffff broadcast 172.16.16.1
	media: Ethernet autoselect (1000baseTX <full-duplex>)
	status: active
	vlan: 11 parent interface: em0
