In a VXLAN BGP EVPN architecture,EVPN Type 5 routes, also known asIP Prefix routes, are used to advertiseLayer 3 reachability informationbetween VXLAN segments. These routes are essential for implementing inter-VNI communication and external network connectivity through distributed or centralized gateways.

According to HCIP Datacom Campus Network documentation, a Type 5 route carriesIP prefix information, including theIP prefix and its prefix length, allowing VTEPs to learn network-level routing information rather than host-level details. TheRoute Distinguisher (RD)is also included to ensure uniqueness of routes across different VPN instances, which is critical in multi-tenant environments. Additionally, thegateway IP addressis carried to identify the next-hop gateway responsible for forwarding traffic toward the advertised prefix.

Unlike EVPN Type 2 routes, which advertiseMAC address and optional host IP address information, Type 5 routes donotcarry MAC addresses. Type 5 routes operate purely at the Layer 3 level and are independent of Layer 2 forwarding. Their purpose is to exchange subnet-level routing information rather than endpoint-level details.

MAC addresses are only relevant for Layer 2 forwarding and ARP/ND suppression, which are functions of EVPN Type 2 routes. Including MAC information in Type 5 routes would be unnecessary and inefficient for Layer 3 routing purposes.

Therefore, the field that isnot carriedin a BGP EVPN Type 5 route is theMAC Address, making optionCthe correct answer.

The Huawei CloudCampus Solution adopts afour-layer architecture, not a three-layer one. According to HCIP Datacom Campus Network documentation, the architecture consists of theterminal layer,network layer,management and control layer, andapplication layer.

Theterminal layerincludes user devices such as PCs, mobile terminals, IoT devices, and other endpoints that access the campus network. Thenetwork layeris responsible for data forwarding and includes access, aggregation, and core network devices. Themanagement and control layer, represented by platforms such as iMaster NCE-Campus, provides centralized management, automation, policy control, and orchestration. Theapplication layerdelivers value-added services and business applications.

Because the terminal layer is an essential and explicitly defined component of the CloudCampus architecture, stating that the solution has only three layers is incorrect. Therefore, the statement isFALSE, making optionBthe correct answer.

In the Huawei free mobility solution based on iMaster NCE-Campus,IP-security groupsare used to associate user identities with IP addresses so that consistent security policies can be enforced regardless of user location. Apolicy enforcement point (PEP)must obtain IP-security group entries to correctly match traffic against security policies.

When the policy enforcement pointis not an authentication point, it cannot directly learn user identity information during access authentication. In this scenario, one supported method is to configureIP-security group entry subscriptionon iMaster NCE-Campus. After subscription is configured, iMaster NCE-Campus pushes the corresponding IP-security group entries to the policy enforcement point, which matches option A.

Another valid approach in this case is described in option B. If the authentication point and policy enforcement point are separate devices, theauthentication point can push IP-security group entriesto the policy enforcement point after successful user authentication. This ensures that enforcement devices receive real-time identity information.

If the policy enforcement pointalso functions as an authentication point, it can directly interact with iMaster NCE-Campus. In this scenario, iMaster NCE-Campusproactively pushes IP-security group entriesto the device, as stated in option C.

Option D is incorrect because iMaster NCE-Campus does not push IP-security group entries indiscriminately in all scenarios. The distribution mechanism depends on the role of the device and whether subscription or authentication-based pushing is configured.

Therefore, the correct answers are A, B, and C.
