Hi,
Assuming you are asking about a L3VPN scenario, the routes learnt from the CE will not show in the P as such. The P router simply use MPLS labels to get traffic from one PE to another and does not need to learn the VPNv4 routes. Could you please explain why do you need the P to learn that specific route.
