This works: "ip route vrf PROD 155.198.60.248 255.255.255.255 vl600
155.198.60.248"

I've used this in the lab to export "host routes" from a VRF.

I messed with the unnumbered VLAN scenario. Didn't really like the
DHCP dependency though, especially as a router reload will then cause
significant problems.
