successfully propagated from the CE router to the ingress PE router, but they are not showing up
on the egress PE router. What is the most likely cause of the problem?
A.There is a BGP-to-MPBGP redistribution error on the ingress PE router.
B.There is a MPBGP-to-BGP redistribution error on the egress PE router.

egress PE routers into two LSPs.
D.RTs attached to the CE routes exported by the ingress router are not matched by at least one of the
import RTs on the egress PE router.
E.A route reflector is used to propagate the routes from the ingress PE router to the egress PE router,
thus breaking the LSP.

customer routes, transporting them across the service provider backbone, and finally propagating them to
other customer sites.
C.With peer-to-peer VPNs, the service provider is responsible for transport of Layer 2 frames between
customer sites, and the customer takes responsibility for all higher layers.

technologies like X.25, Frame Relay or ATM.
E.With Layer 2 overlay VPNs, the service provider is not aware of customer routing and has no
information about customer routes.
F.It is simple to implement Layer 2 overlay VPNs because the Customer Edge (CE) router just needs a
