In Huawei’s CloudFabric Solution, the underlay network provides the physical infrastructure for VXLAN overlays. Both OSPF (Open Shortest Path First) and BGP (Border Gateway Protocol) are supported routing protocols:
OSPF:Suitable for smaller to medium-sized DCNs, offering fast convergence and simplicity.
BGP:Preferred for large-scale DCNs, providing scalability and multi-tenancy support (e.g., EBGP for inter-AS or iBGP for intra-DC).
Huawei documentation confirms flexibility in choosing OSPF or BGP based on network size and requirements. The statement isTRUE (A).References:Huawei CloudFabric Data Center Network Solution – Underlay Protocols; HCIP-Data Center Network Training – Routing Options.
