In this chapter we will cover how to configure L3 Outs using OSPF as the routing protocol and then classifying external prefixes into ACI through External EPGs. We will show all the steps needed so that you can perform this successfully through the wizard and following the traditional step-by-step approach. I will also show you some commands and places to verify your configuration and we will briefly cover some use cases for MPLS/SR handoff and GOLF L3 Outs.
