(Which of the following is used to implement inter-subnet communication on a VXLAN network and allow access from a VXLAN network to an external non-VXLAN network?)
Comprehensive and Detailed 200 to 250 words of Explanation From HCIP Datacom Campus Network documents knowledge without any URL or Links:
In VXLAN-based networks, inter-subnet communication and external network access requireLayer 3 forwarding capabilities. ALayer 3 VXLAN gatewayperforms routing between different VXLAN segments (VNIs) and enables traffic to exit the VXLAN overlay toward traditional non-VXLAN networks.
The NVE interface is responsible only for VXLAN encapsulation and decapsulation and does not perform routing. VLANIF interfaces are used in traditional VLAN environments and do not provide VXLAN interworking. A Layer 2 VXLAN gateway supports bridging only and cannot route between subnets.
Therefore, the Layer 3 VXLAN gateway is the correct solution for inter-subnet communication and external access.
