>Description:
ifconfig inet command doesn't install "directly connected" route if this route is already in routing table with other flags. In my case I use quagga for redistributing connected routes:
svm.sigma24.ru# show ip route 83.143.32.32/28
Routing entry for 83.143.32.32/28
Known via "ospf", distance 110, metric 20, best

* 83.143.32.9, via vlan4
svm# ifconfig vlan6 create
svm# ifconfig vlan6
