Which statement about MPLS VPN implementations and traditional peer-to-peer VPN implementations is true?
A.
MPLS and traditional peer-to-peer VPNs require the service provider to participate in the customer routing.
B.
MPLS and traditional peer-to-peer VPNs require that the customer routing is transparent to the service provider.
C.
MPLS VPNs require the use of link-state routing protocols, traditional peer-to-peer VPN implementations require distance vector protocols.
D.
MPLS VPNs are constructed using dynamic routing protocols; traditional peer-to-peer VPN implementations are constructed using static routes.
Explanation:
The provider IS participating in the customer routing. Peer-to-Peer VPN’s require the SP to participate in customer routing, accepting customer routes, transporting them across the SP backbone and propagating to customer sites. The Provider routers carry all the customers routes, they are easy to implement, optimum routing is enabled between sites by default as a result.
