Designing Cisco Enterprise Networks (ENSLD) — Question 186
An engineer is designing a BGP solution supporting a VXLAN environment over a Layer 3 IPv4 network fabric with these requirements:
• provide Layer 2 adjacency
• allow VM migration of workloads between sites
• IGP is OSPF
Which BGP address family must the engineer choose?
Answer options
- A. L2VPN VPLS-VPWS
- B. L2VPN EVPN
- C. IPv4 unicast
- D. VPNv4
Correct answer: B
Explanation
The correct answer is B, L2VPN EVPN, as it is specifically designed to provide Layer 2 services over a Layer 3 infrastructure and supports features like VM mobility. Option A, L2VPN VPLS-VPWS, does not inherently facilitate VM migration between sites, while options C and D are not designed for Layer 2 adjacency in a VXLAN context.
