MPLS Multi-vrf and IP Multicast

Hello All, Any scenario where we are using MPLS between PE-CE when CE is multi-vrf router, any deployment in real word? Carrier supporting carrier CSC is one where you have MPLS between PE-CE link. If PE-CE running MPLS between them then what will be impact on MULTICAST between two site? If PE-CE connectivity is pure IP then i think multicast will work properly right? thanks, Devang Patel
