Which of the following statements is incorrect about a BGP/MPLS IP VPN?
A.
In most cases, CEs are unaware of VPNs and do not need to support MPLS or MP-BGP.
B.
A BGP/MPLS IP VPN consists of customer edges (CEs), provider edges (PEs), and providers (Ps). PEs and Ps are carrier devices, whereas CEs are BGP/MPLS IP VPN customer devices.
C.
Inter-site communication can be implemented through VPN. A site can only belong to only one VPN.
D.
Ps only need to provide basic MPLS forwarding capabilities and do not need to maintain VPN-related information.
The Answer Is:
C
This question includes an explanation.
Explanation:
The incorrect statement is Option C, which says “A site can only belong to only one VPN.” This is false because a single site can belong to multiple VPNs if needed. For example, in some enterprise designs, a site may be part of both the Finance VPN and the Management VPN by configuring multiple routing instances (VRFs) and policies accordingly.
