Cisco vFTD integration in ACI using PBR Service Graph redirection

Solution Overview
The use of a single bridge domain in ACI brings a FW integration challenge as a typical L4-7 service requires a separate bridge domain for each FW interface. Given that a true Application Centric approach typically requires a single bridge domain with multiple subnets, forcing traffic through a FW or LB has a great deal of challenges in the design. By utilizing a service graph and PBR (policy-based redirection) traffic can be redirected from this single bridge domain to a single interface on the FW or LB. A very large caveat is that some FW vendors do not allow traffic to come in and exit the same interface. There are a few vendors that can do this one-armed mode and we will show the Cisco FTD-based solution using the virtual Cisco FTD known as the Cisco vFTD. 

Goals & Objectives

The goal of this lab is to show the ACI engineer how to integrate a virtual Cisco FTD FW into ACI using PBR redirection
In this lab you will
  • Create New bridge domains and PBR redirection policies
  • Create L4-7 devices, service graphs and device selection policies
  • Attach service graphs to contracts
  • Validate redirected traffic to the Cisco vFTP using the FMC console.

Hardware & Software

This will be accomplished by utilizing components in the Cisco ACI product portfolio. The components used include: 
  • ACI running version 4.0 code 
  • vCenter 6.5 
  • Cisco vFTD running 6.2.2 
  • FMC 6.2.2
