dynamic failover for certain networks

Level 1
Level 1

Network:

Core_RTR-(2)- 172.16.2.x-(1)----C65K---(254)--172.16.1.X--(253)--WAN RTR#1-(5)--192.168.3.0-(6)-{AS 65001}---MPLS#1-{AS 4182}--(AS65001)--Stub Sites
   |                                      EIGRP                                         EIGRP/BGP                                                                                        BGP

172.16.253.2/30        
    | EIGRP

MPLS #2   <-------This cloud is injecting 4 prefixs into EIGRP*****
  |   EIGRP

172.16..253.10/30

  |
  | EIGRP/BGP                                                                                                   BGP
WAN_RTR#2---192.168.7.8------{AS 65002}-(5)----------------------------------------MPLS#1-{AS 4182}---------------------------(AS65001)--Stub Sites(same as above)


***The goal is to enable dynamic failover for the following networks if the connection from MPLS#2 fails on Core_RTR to transverse via WAN_RTR#2

Network 10.4.32.0/24

Network 10.1.128.0/24

Network 192.168.50.0/24

WAN_RTR1 and WAN_RTR2 are connected to the same ISP and provide connectivity to the stub sites incase of failure. The prefixes from MPLS#2 need to be redundant via either WAN_RTR#1 or WAN_RTR#2

As these networks need to be reachable from the stub sites if the connection from MPLS#2 is lost on the Core_RTR. The question is do I redistribute these prefixes from EIGRP {which they currently are as we are receiving them MPLS#2 as type EX with a AD 170} into BGP or do I originate them via the network command in BGP and pre-pend the paths from each AS?

Any suggestions?

Thanks

Any chance of a jpg showing the network layout. The above is somewhat difficult to read
