In Huawei CloudFabric Solution, OSPF or BGP can be used on the underlay network of a DC.

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 is TRUE (A).
