What does the VXLAN source port add to the overlay packet forwarding when it uses the hash of Layer 2, Layer 3, and Layer 4 headers of the inner packet?
The correct answer is A. ECMP. The VXLAN source port adds entropy to the overlay packet forwarding by using a hash of the inner packet's Layer 2, Layer 3, and Layer 4 headers. This entropy enables Equal-Cost Multi- Path (ECMP) routing, allowing for multiple parallel paths in the network, which increases…

Explanation
The VXLAN source port adds entropy to the overlay packet forwarding by using a hash of the inner packet's Layer 2, Layer 3, and Layer 4 headers. This entropy enables Equal-Cost Multi- Path (ECMP) routing, allowing for multiple parallel paths in the network, which increases bandwidth and redundancy. ethernet-virt.html
