Huawei Certified ICT Expert – Data Center Network (HCIE-DCN) — Question 2

Regarding MP-BGP, which of the following description is incorrect?

Answer options

• A. When the PE and CE exchange routes through BGP, you need to create a BGP process for each VPN instance on the CE
• B. MP-BGP's message type and VPNv4 routing policy are the same as BGP-4
• C. MP-BGP needs to assign private network labels to VPNv4 routes
• D. MP-BGP advertises VPNv4 routes through two attributes: MP_REACH_NLRI and MP_UREACH_NLRI

Correct answer: B

Explanation

Option B is incorrect because while MP-BGP shares similarities with BGP-4, it specifically introduces the concept of VPNv4 routes and their associated attributes, which are not present in standard BGP-4. The other options accurately describe the requirements and functions of MP-BGP in relation to VPN instances and routing attributes.
