Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 388

Which two components are needed for a service provider to utilize the L3VPN MPLS application? (Choose two.)

Answer options

• A. The P routers must be configured with RSVP.
• B. The PE routers must be configured for MP-eBGP to connect to CEs.
• C. The P routers must be configured for MP-iBGP toward the PE routers.
• D. The PE routers must be configured for MP-iBGP with other PE routers.
• E. The P and PE routers must be configured with LDP or RSVP.

Correct answer: D, E

Explanation

The correct answers are D and E because PE routers must use MP-iBGP to communicate with other PE routers and both P and PE routers need to be configured with LDP or RSVP for label distribution. Options A, B, and C are incorrect as they either pertain to configurations that are not essential for L3VPN MPLS or focus on incorrect router types.
