Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 616

Which two NLRI attributes are used by an MPLS Layer 3 VPN network to exchange VPNv4 routes between MPLS routers via MP-BGP? (Choose two.)

Answer options

• A. VPNv4 Prefix
• B. Next Hop
• C. Extended-Community
• D. IPv4 Prefix
• E. RT

Correct answer: B, D

Explanation

The correct attributes for exchanging VPNv4 routes in an MPLS Layer 3 VPN are the Next Hop and IPv4 Prefix. The Next Hop attribute is crucial for determining the next router in the path, while the IPv4 Prefix is necessary to identify the destination. The other options, while relevant in different contexts, do not specifically pertain to the exchange of VPNv4 routes in this scenario.
