MPLS VPN L3 question CISCO ?

Hey guys I trying to understand and configure a simple l3 mpls vpn, I am using a previously topology where I had a service provider with bgp + ospf. Now I configured mpls over this topology. And looks fine, but I am with problems to understand:

I decided to use rip between my CE <--> PE so I did this in the PE:

vrf definition CLIENT2-1 rd 120:120 address-family ipv4 route-target export 20:20 route-target import 30:30 router bgp 30 address-family vpnv4 neighbor 172.30.3.3 activate - neighbor 172.30.3.3 send-community extended address-family ipv4 vrf CLIENT2-1 redistribute rip router rip address-family ipv4 vrf CLIENT2-1 redistribute bgp 30 metric 2 network 172.70.70.0 network 10.0.0.0 interface FastEthernet0/0 description CONNECTION-TO-CLIENT2-1 vrf forwarding CLIENT2-1 ip address 10.100.37.2 255.255.255.252 duplex half end 

In the CE "customer edge" side I did this:

vrf definition CLIENT2-1 rd 120:120 network 10.0.0.0 network 172.70.0.0 no auto-summary exit-address-family 

Makes sense ? dindt work ... :(

my client "CE" has this lan 172.70.70.0/26

my network between CE-PE is 10.100.37.0/30

​

Thanks a lot for any help.
