How to provied Redundancy for VRF MGMT with help of BGP over MPLS(MPBGP)

Question

Hi,
Please find the Network Topology.
This is One Remote site and mamaged by Mgmt office.
All devices on remote site is accessed by MGMT Office. My organisation seek for Redundancy for Managing devices.
My administration is from MGW to R1. I am new to MPLS.
AS u can see in diagram, R1 have 3 VRF(Voice,Signal and MGMT).Currently i have primary link over whitch we are running MPBGP.
Traffic from these VRF goes to this primary link. Currently Secondary link is not connected.
Now my organisation proposed for  the  secondary  link  and they want that only traffic from VRF -- MGMT should go through MPLS RTR R2 (the secondary link ) , when the mgmt routes  not learned from MPLS  RTR R1 (Connected to the SP1 ).
Current  R1 config
There is IBGP betweem R1 to both MPLS RTR.
BGP Config
router bgp 64513
  synchronization disable
  neighbor 10.36.150.1 remote-as 64513
  neighbor 10.36.150.1 activate
  neighbor 10.36.150.1 update-source loopback1
  address-family ipv4 vrf signalling
    redistribute connected
    redistribute static
  $
  address-family ipv4 vrf voice
    redistribute connected
    redistribute static
  $
  address-family ipv4 vrf OAM-T
    redistribute connected
    redistribute static
  $
  address-family vpnv4
    neighbor 10.36.150.1 activate
    neighbor 10.36.150.1 send-community
  $
!<ospfv2>
router ospf 100
  interface gei-3/3
    network point-to-point
  $
  network 10.36.150.49 0.0.0.0 area 0.0.0.0  --- loopback ip (Configured)
  network 10.36.149.60 0.0.0.3 area 0.0.0.0 ---- p2p ip bet R1 and MPLS R1.(Configured)
network 10.36.149.64 0.0.0.3 area 0.0.0.0 ---- p2p ip bet R1 and MPLS R2. ----------  (till now not configured as secondary link is not connected)
router-id 10.36.150.49
so what configuration need to done at R1  to achiev the redunancy for MGMT vrf ?
if possible please reply with sample configuration.
or
IN MPBGP protocol, where i will apply routing policy to apply  as- path prepand    so that Route  would be secondary to  neighbor.
IGP-OSPF and BGP over MPLS is running.
on Which  address-familiy nbr,should i apply, is it in VPNV4 or IPV4 or IPV4  VRF ?
if i want 10.36.128.0/26 prefix should go to Neigbhor MPLS R2, what should i use access-list or Prefix list?
please provide the reply with its config .
thanks in advance,
Regards,
Ajay
