Can you solve this puzzle?
R2, R3 and R4 create the service provider network, with MPLS on all three routers, and iBGP at the PE routers.  R1 and R5 are the CE routers.
R2, prefers the BGP next hop of 4.4.4.4 for network 5.5.5.5 (R5 loopback). R4, at 4.4.4.4 is an iBGP neighbor.

R2#show ip route vrf v | inc 5.5.5.0
B       5.5.5.0 [200/409600] via 4.4.4.4, 00:06:47

Is R2 preferring an iBGP learned route, which has an AD of 200, over a EIGRP route, which would have an AD of 90?
Can you identify why the routing for 5.5.5.0 on the VRF of R2 is using BGP instead of EIGRP?

Below are the relevant portions of the configuration, which also can serve as a great review of how to configure MPLS VPNs.

Now for a couple show commands on R1:

R1#show ip route eigrp
