In iMaster NCE-Campus–based virtualized campus networks,user network segmentsare logical subnets created within aVirtual Network (VN)to provide Layer 2 or Layer 3 connectivity for users. HCIP Datacom Campus Network documentation describes multiple flexible methods for creating these network segments during VN deployment, allowing administrators to balance efficiency and control.
Administrators canmanually create user network segments one by one, which is suitable for small-scale deployments or scenarios requiring precise customization of subnet parameters such as gateway address, VLAN, and IP pool. This method provides maximum control but is less efficient for large networks.
For medium- or large-scale deployments,batch import using templatesis widely supported and recommended. Templates allow administrators to define network segment parameters in advance and import multiple segments at once, significantly improving deployment efficiency and reducing configuration errors.
Another supported method isautomatic batch allocation, where iMaster NCE-Campus automatically allocates VNIs, VLANs, and IP resources from predefined resource pools. This method is commonly used in VXLAN Fabric deployments and enables fast, standardized VN provisioning with minimal manual input.
However,directly invoking user network segments from the global fabric resource poolis not supported during VN creation. The global resource pool is used for automatic allocation reference but does not allow direct binding of pre-created segments to a VN.
Therefore, the valid methods aremanual creation,template-based batch import, andautomatic batch allocation, making optionsA, B, and Dcorrect.
