In Huawei CloudFabric architecture, server leaf nodes and service leaf nodes have distinct roles, even though both can function as NVEs (Network Virtualization Edge devices) in a VXLAN network.
A server leaf node primarily provides access for compute resources , such as physical servers and virtual machines. It acts as a common NVE, handling VXLAN encapsulation/decapsulation for tenant traffic and enabling communication within the overlay network.
However, firewalls and load balancers (LBs) are classified as value-added service (VAS) devices and are typically connected to service leaf nodes , not standard server leaf nodes. Service leaf nodes are specifically designed to handle service insertion, traffic steering, and policy-based forwarding required for these devices.
Although in some simplified deployments roles may be combined, Huawei standard design clearly separates:
Server leaf → compute access
Service leaf → VAS device access (FW, LB, etc.)
Therefore, the statement is FALSE , as server leaf nodes do not typically provide access for firewalls and load balancers in standard CloudFabric architecture.
