In HCIP Datacom Campus Network VXLAN architecture, VXLAN tunnels are classified based onhow the tunnel endpoints are created and maintained, which is referred to as the VXLAN tunnel creation mode. According to Huawei VXLAN design principles, there aretwo valid VXLAN tunnel types: static VXLAN tunnels and dynamic VXLAN tunnels.
Astatic VXLAN tunnelis manually configured by an administrator. In this mode, the source VTEP IP address, destination VTEP IP address, and related parameters are explicitly specified on devices. Static VXLAN tunnels are typically used in small-scale networks or test environments where the number of VTEPs is limited and network topology is simple. However, static configuration lacks scalability and flexibility, making it unsuitable for large campus fabrics.
Adynamic VXLAN tunnelis automatically created based on control-plane learning mechanisms, such asBGP EVPN. In this mode, VTEPs learn remote VTEP IP addresses dynamically through EVPN route advertisements (for example, Type 3 routes). When a remote VTEP becomes reachable at the underlay Layer 3 level, the VXLAN tunnel is automatically established without manual intervention. This mode is widely used in modern campus and data center networks due to its scalability and automation capabilities.
Options A and D are incorrect becausestatelessandstatefulare not official VXLAN tunnel creation classifications in Huawei’s VXLAN implementation. VXLAN itself is an encapsulation mechanism, and tunnel state is not categorized in this manner.
Therefore, the correct VXLAN tunnel types based on creation mode arestatic VXLAN tunnels and dynamic VXLAN tunnels.
