In a CloudCampus VXLAN fabric,node role planningis a fundamental design task that directly affects scalability, performance, and manageability. Huawei defines clear roles for fabric nodes, includingedge nodes,border nodes, and optionallyroute reflectors (RRs).
Statements A, B, and C correctly describe recommended design practices. Core devices are commonly deployed asborder nodesbecause they have higher performance and are well suited to connect the VXLAN fabric to external networks such as WANs or data centers. Access or aggregation devices acting asedge nodesenable end-to-end VXLAN automation and allow user traffic to be encapsulated and decapsulated close to the access layer. Additionally, when external networks exist in different physical locations, deployingmultiple border nodesimproves reliability and optimizes traffic paths.
Statement D is incorrect. In a VXLAN network usingBGP EVPN with route reflectors,edge nodes do not need to establish BGP peer relationships with each other. Instead, edge nodes establish BGP EVPN peer relationshipsonly with the RR, which centrally reflects EVPN routes to other nodes. This design significantly reduces the number of BGP sessions and improves scalability in large networks. Border nodes may also peer with the RR, but full-mesh peering between edge nodes is not required.
Therefore, the false statement isD, making it the correct answer.
