Import the proper route-targets in VRF RED and VRF BLUE.

ip vrf RED
 rd 123:111
 route-target import 123:111
 route-target import 123:222
 route-target export 123:111

ip vrf BLUE
 rd 123:222
 route-target import 123:222
 route-target import 123:111
 route-target export 123:222

You can also just import+export from/to one of the VRFs. Might need to
attach import/export maps to filter which routes you'd like to
import/export.

To my knowledge there's no way to run EIGRP (or any other routing
protocol) between two different VRFs (unless you stich them via a CPE)
