I have a router that I configured to emulate the MPLS network of a customer. Each customer sites are connected to this router and have a EIGRP adjacency with it. On the MPLS router, a VRF has been configured for each sites and route leaking is used for route exchange between the VRF.
It works but there is something that is puzzling me. On the customer sites routers, the routes for the other sites appear as EIGRP Internal routes. Since these routes are being redistributed from EIGRP to BGP and then from BGP to EIGRP I would have expected them to be external. Does anyone know why the routes are internal?
Here is the relevant part of the config of the MPLS router:
ip vrf HQ
rd 65000:1
route-target export 65000:1
route-target import 65000:2
route-target import 65000:3
!
ip vrf Remote1
rd 65000:2
route-target export 65000:2
route-target import 65000:1
route-target import 65000:3
!
ip vrf Remote2
rd 65000:3
route-target export 65000:3
route-target import 65000:1
route-target import 65000:2

The routes on one of the customer router:
Remote1#sh ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
+ - replicated route, % - next hop override
