CPOC Series: ACI Service Chaining using Policy Based Redirect (PBR) for east-to-west traffic through an ASA FW

August 1, 2020

In this video we explore using Policy Based Redirects to identify either a subset or ALL traffic between EPGs and forcing that traffic to an external device, in our case, an ASA FW. In our case, our ACI Fabric is the L3GW for all traffic. With the PBR feature, we are going to use an … More CPOC Series: ACI Service Chaining using Policy Based Redirect (PBR) for east-to-west traffic through an ASA FW
