The oversubscription ratio in an IP fabric is influenced by the number of spine nodes relative to the number of leaf nodes and their uplinks.

Removing spine nodes reduces available uplink bandwidth, increasing oversubscription.

Adding spine nodes increases available bandwidth between leafs and spines, decreasing the oversubscription ratio.

Modularity in network design allows for easier scalability, troubleshooting, and future upgrades by segmenting the network into functional blocks. This approach simplifies management and enhances the network's ability to adapt to changing requirements.

VXLAN and MPLS are commonly used to encapsulate frames and provide Layer 2 reachability across an IP fabric. VXLAN enables L2 overlays over L3 infrastructure, while MPLS can also be used in L2VPN services to extend L2 connectivity across IP/MPLS networks.
