Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 414
In a typical MPLS VPN, which routers act as the MPLS label imposition and disposition points in the network?
Answer options
- A. CE Router
- B. P router
- C. PE Router
- D. Core router
Correct answer: C
Explanation
The correct answer is C, PE Router, as these routers are specifically designed to handle MPLS label operations by imposing and disposing of labels for VPN traffic. CE Routers are customer-facing and do not perform label operations, while P Routers are responsible for the transport of labeled packets but do not impose or dispose of labels themselves. Core routers typically refer to high-capacity routers in the backbone of the network and may not specifically deal with MPLS label operations.
