Which technology does VXLAN use to provide segmentation for Layer 2 and Layer 3 traffic?
Which technology does VXLAN use to provide segmentation for Layer 2 and Layer 3 traffic?
VXLAN (Virtual Extensible LAN) uses Virtual Network Identifier (VNI) to provide segmentation for Layer 2 and Layer 3 traffic. The VNI is a 24-bit field within the VXLAN header that uniquely identifies the VXLAN segment, similar to how VLAN IDs are used but with a much larger addressing space, allowing for over 16 million unique VXLAN segments.
VXLAN Network Identifier (VNI)
Mac-in-IP/UDP encapsulation
A VXLAN header that includes a 24-bit field—called the VXLAN network identifier (VNI)—that is used to uniquely identify the VXLAN. The VNI is similar to a VLAN ID, but having 24 bits allows you to create many more VXLANs than VLANs.

C is correct
voting. provided answer is correct
Given answer is correct
the correct answer is bridge domain. the VNI is not a technology, its only a vxlan representation of the bridge domain, who is the underlying technology. how do you configure a VNI? you have to map it to a bridge domain. the bridge domain is a layer 2 space just like vlan and the vni is associated to it
C is correct
Why not VRF? because its applied on L3?
C is correct
