A. It is the only option to provide reachability between servers that reside in the same network segment in a data center.
B. BGP provides the control plane within the overlay network.
C. An encapsulation of the original packet is required to transport the packet across the network.
D. OSPF provides the control plane within the overlay network.
Explanation:
EVPN-VXLAN is an overlay technology used in data center networks to extend Layer 2 services over a
Layer 3 network.
Step-by-Step Breakdown:
BGP Control Plane:
BGP (Border Gateway Protocol) is used as the control plane for EVPN-VXLAN. BGP advertises MAC addresses and IP address reachability information across the VXLAN network, enabling efficient multi-tenant Layer 2 connectivity over a Layer 3 infrastructure.
Encapsulation:
VXLAN (Virtual Extensible LAN) encapsulates Layer 2 frames into Layer 3 packets. This encapsulation allows Layer 2 traffic to be transported across a Layer 3 network, effectively creating a tunnel for Ethernet frames.

Reference: EVPN-VXLAN Configuration: Juniper supports EVPN-VXLAN with BGP as the control plane, allowing scalable Layer 2 connectivity over a routed infrastructure in modern data centers.
