Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 201
Which two components are required for MPLS Layer 3 VPN configuration? (Choose two.)
Answer options
- A. Use LDP for customer routes.
- B. Use pseudowire for Layer 2 routes.
- C. Use a unique RD per customer VRF.
- D. Use OSPF between PE and CE.
- E. Use MP-BGP for customer routes.
Correct answer: C, E
Explanation
The correct answers are C and E because a unique Route Distinguisher (RD) is necessary to differentiate VPN routes in the VRF, and MP-BGP is used to exchange routing information between MPLS routers for each customer's routes. Options A, B, and D are not required components for MPLS Layer 3 VPN configuration.
