Nexus 7010 - redistribute host routes in to OSPF

Question

In my Nexus 7010 infrastructure, I have a requirement to redistribute host routes in to OSPF so that the other connected sites receive the host routes through OSPF.
These hosts are part of the connected network (192.168.100.0/24) on Nexus, I dont want this network to be advertised in to OSPF but I want the hosts inside this subnet (192.168.100.11 and 192.168.100.12) to be advertised.
I tried to create a prefix list with these two hosts and added them to a route-map and then using the "redistribute direct" command called this route-map in to OSPF, but this is not working.
However, if I add the entire subnet (the connected network) in to this route-map, it shows up in OSPF.
Is there a way I could have only the hosts to be part of the OSPF database?

Hello, There is no need for VDC or VRF I think. are we missing a trick here. I also just tested for my own sanity. (Or am I completely under-thinking this)
N7K-1 has vlan 24 and the host route will be to 172.25.24.20
N7K-1 Config:
conf t
ip route 172.25.24.20/32 Vlan24
ip prefix-list TEST seq 5 permit 172.25.24.20/32
route-map STATIC_TO_OSPF permit 10
  match ip address prefix-list TEST
router ospf 1
  bfd
  router-id 192.168.101.1
  redistribute static route-map STATIC_TO_OSPF
here is what I see on its neighbour N7K2:
DC1-N7K2# show ip route 172.25.24.20
IP Route Table for VRF "default"
'*' denotes best ucast next-hop
'**' denotes best mcast next-hop
'[x/y]' denotes [preference/metric]
'%<string>' in via output denotes VRF <string>
172.25.24.20/32, ubest/mbest: 1/0
    *via 192.168.102.5, Eth8/1, [110/20], 00:00:07, ospf-1, type-2
DC1-N7K2#
                Type-5 AS External Link States
Link ID         ADV Router      Age        Seq#       Checksum Tag
172.25.24.20    192.168.101.1   479        0x80000002 0x0eed    0
So in essence point the host routes statically to the directly connected interface.
