If you use VRF correctly, it will work ;)
two things:
1. paste "show run" configuration of all those interfaces that you are trying to advertise on R1. Are they all configured in "ip vrf forwarding GIT"? see my previous message
2. "capability vrf-lite" is a command that you might need under OSPF. But if you only have OSPF and no redistribution from BGPvpnv4 into OSPF, then you don't need it.
