質問 # 46
(It is recommended that the IP address of a loopback interface instead of the IP address of a physical interface on a device be used as a VTEP IP address of a VXLAN tunnel.)
A. TRUE
B. FALSE
正解：A
解説：
In Huawei CloudFabric and VXLAN-based data center designs, it is a best practice to use the IP address of a loopback interface as the VTEP (VXLAN Tunnel End Point) source address instead of a physical interface IP.
This recommendation is based on reliability, stability, and operational flexibility.
A loopback interface is always in the UP state as long as the device is operational, whereas physical interfaces may go down due to link failures. If a physical interface IP is used as the VTEP source, any link failure would cause VXLAN tunnels to flap, impacting service continuity. In contrast, loopback interfaces remain reachable through the underlay network via dynamic routing protocols such as OSPF, IS-IS, or BGP, ensuring consistent tunnel endpoints.
Additionally, using loopback addresses supports ECMP (Equal-Cost Multi-Path) forwarding in the underlay, improving load balancing and network utilization. Huawei documentation strongly emphasizes this design principle to enhance VXLAN tunnel resilience and simplify network operations. Therefore, the statement is TRUE.
