What is the main reason SD-Access uses VXLAN data encapsulation instead of LISP data encapsulation?
- VXLAN supports IPv6.
- VXLAN supports Layer 2 networks.
- VXLAN has a much smaller header.
- VXLAN has a better ring to it.
Explanation: Although LISP is the control plane for the SD-Access fabric, it does not use LISP data encapsulation for the data plane; instead, it uses VXLAN encapsulation because it is capable of encapsulating the original Ethernet header, and this allows SD-Access to support Layer 2 and Layer 3 overlays.
