B. CEF switching is only needed to forward labeled packets.
C. CEF switching is needed on both ingress and egress interfaces on which MPLS is enabled.
D. Interface-level CEF switching is needed only on egress interfaces that are sending IP packets on which the egress LSR performs the label imposition process.

C. If the PE-CE protocol is not BGP, redistribution of other VPN routes from MP-BGP is required.
D. If RIP is the routing protocol that is used between the PE-CE routers, no redistribution is required, but any other protocol will require redistribution.
E. If using OSPF or EIGRP as the PE-CE routing protocol, redistribution is not required, but any other protocol or static route will require redistribution.
