yes as pre the design.

This is a standard design of ACI. Spines and Leafs have very different functions. The only connections possible with Spines are to Leaf nodes and fabric Infrastructure connections (ie. GOLF, InterPod/InterSite Network only). All L3 connections for User workloads need to be connected to Leafs. The leafs maintain the routing tables, and redistribute of prefixes into MP-BGP and and corresponding VRFs. The Spines primary function is more of a backplane to the fabric though it doubles as the global endpoint policy manager (COOP Oracle). Leafs are where all endpoint classification and policy is applied. When I explain the function of Spines & Leafs, I use the analogy of a giant logical switch. The spines act as your fabric modules providing the interconnection, and Leafs are the Linecards in which all workloads are connected into.
Hope this helps.
