Which two statements about MPLS VPN implementations and traditional peer-to-peer VPN implementations are true? (Choose two)
A.
In MPLS VPNs, the PE-routers are aware of the customer routes.
B.
In MPLS VPNs, the PE-routers are not aware of the customer routes.
C.
In traditional peer-to-peer VPN implementations, the PE-routers are aware of the customer routes.
D.
In traditional peer-to peer VPN implementations, the PE-routers are not aware of the customer routes.
Explanation:
A: Since in MPLS VPN, PE and CE still need to exchange routing information then propagate through MP-iBGP. in peer-to-peer VPNS, PE and P routers ARE in customer’s network, of course they exchange routing information. Peer-to-peer routers are visible to customers because they are INSIDE the customer network, so B cannot be correct.
