I have same problem on ROS7.1.1 Maybe now someone has achieved the work of VPNV4 or, as I understand it correctly, there is still no solution?

Some light now, mp-bgp vpnv4 working okay in version 7.3 from my labs as per below, so far soo good. mpls labels still missing , will definitely run further tests on this.
Great job @mikrotik team, appreciated

Re: MP-BGP VPNV4 not working

Hello.
I'm using ROS 7.5
I have assembled a circuit between two CCR2004-16G-2S +, if you specify vrf in the bgp connection, the bgp session does not rise.

Someone faced similar?
Does MP-BGP work at all in Router OS 7?

this is my topology, P1 also is a route reflector, MPLS is working but the advertise prefix from CE1 192.168.20.0/24 (route flag daY) via OSPF is keep on flapping on PE2
