Inter-VPN routing with export map for host routes

Question

Hi,
I am trying to export host routes from a connected network from one VRF to multiple other VRFs. This is to allow the leaking specific host routes for management purposes. However, I suspect that the /32 host route(s) actually need to be present in the management VRF so the RTs are added accordingly, rather than just specified in the match clause of the MGMT VRF export map.
Ideally here, I only want to export 10.111.111.254/32 from the connected network 10.111.111.0/24 in the MGMT VRF. The only way around this I can see it to move 10.111.111.0/24 behind another device, and add specific host route(s) within the MGMT VRF for the 10.111.111.X/32 host routes (which are redistributed into the MGMT VRF), using the additional device as the next-hop.
ip vrf MGMT
rd 1:1
export map MGMT-EXPORT-MAP
route-target export 1:1
route-target import 1:1
route-target import 1:1001
ip vrf CUST-B
rd 1:2
export map CUSTOMERS-EXPORT-MAP
route-target export 1:2
route-target import 1:2
route-target import 1:1000

Hi Matt
Yes the X/32 routes needs to be present in the VRF Routing-Table and if they are to be learnt statically then the MP-iBGP config for that particular VRF address-family has to redistribute static routes as well.
