In GNS 3 lab i am tring to transport routes from R32 to R20. (both routers are PE in the MPLS)
In R32 I have a eBGP adjacency with R1 and learning many routes.
In router R32 the rutes adverticed from R1 is inserted in VRF INTERNET:
ip vrf INTERNET
rd 65010:100
import ipv4 unicast map UNICAST
route-target export 65010:100
route-target export 65010:3
route-target import 65010:100
route-target import 65010:3
access-list 50 permit any
!
route-map UNICAST permit 11
match ip address 50
This command used to verify is the rutes ares in VRF INTERNET:
R32#sh ip route vrf INTERNET
Routing Table: INTERNET
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

R32#
All rutes are inserted in VRF INTERNET
Now I would like to transport this VRF Internet to another PE in this case R20.
This is my config in R32:

I am not receiving the rutes and I don´t know why.
Some suggestions?
Thank you.
If need any other config I will post all information.
