Your BGP session between the XR and the ME is only running IPv4 unicast, not M-BGPv4, you can see that in the Neighbor capabilities list doing a show BGP neighbor on ME, where you will see that:

Address family VPNv4 Unicast: advertised

But you have not recieved it, you're missing the following on the XR:

router bgp 1000

 neighbor 3.3.3.3 address-family vpnv4 unicast

commit

 

The clear the BGP session, and let them nengotiate the capabilities, and you should be good then.

BTW you only need a RPL attached for e-bgp neighbors, not for ibgp.
