Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 98

What does the PE router convert the IPv4 prefix to within an MPLS VPN?

Answer options

• A. eBGP path association between the PE and CE sessions
• B. prefix that combines the ASN, PE router-id, and IP prefix
• C. 48-bit route combining the IP and PE router-id
• D. VPN-IPv4 prefix combined with the 64-bit route distinguisher

Correct answer: D

Explanation

The correct answer is D because the PE router creates a unique VPN-IPv4 prefix that incorporates the 64-bit route distinguisher, which helps to distinguish between different VPNs. The other options do not accurately describe the conversion process of the IPv4 prefix in this context.
