Running BGP instead of an IGP in your leaf-and-spine fabric sounds like an interesting idea (particularly if your fabric is large). Configuring a zillion BGP knobs on every box doesn’t.
However, BGP doesn’t have to be complex. In the Simplify BGP Configurations video (part of leaf-and-spine fabric designs webinar) Dinesh Dutt explains how you can make BGP configurations simple and easy-to-understand.
