The video continues to look at Service Graph in Cisco ACI, and show you how to insert a firewall between EPGs. We will be configuring unmanaged firewalls in two different mode; Go-To and Go-Through, using Cisco FTD. We will be exploring with more complex topologies not only with EPG-to-EPG but also EPG-to-L3Out. At the end, we will be experimenting with uSeg EPG.
