Another option in this case would be to add an exit interface
parameter to the static route.
ip route 1.1.1.0 255.255.255.0 vlanX 10.1.1.254
This syntax will specify the next hop ip address and the exit
interface avoiding the recursive lookup issue. When the interface is
down the route will be removed from the routing table.
