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

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

CPOC Series: Achieving Segmentation in ACI by Attaching multiple EPGs to one Bridge Domain

In this video we explore the design practices of attaching multiple EPGs to a BD. There are several use-cases for this, including but not limited to: Application-centric design Not having to re-address servers that you want to split up (i.e., separating web servers from app servers from db servers in the same subnet) Compliance (i.e., … More CPOC Series: Achieving Segmentation in ACI by Attaching multiple EPGs to one Bridge Domain

CPOC Series: ACI Segmentation Using Microsegmented EPGs (uSeg)

In this video we explore a very popular topic in Microsegmentation. To summarize, Microsegmentation inside of ACI is taking devices inside of an EPG, and placing them inside of their own “sub-EPG”. This new EPG behaves exactly like normal EPGs from a connectivity perspective; we still need contracts to talk to other EPGs (including our … More CPOC Series: ACI Segmentation Using Microsegmented EPGs (uSeg)

CPOC Series: Segmentation in ACI using Isolated EPGs

In this video, we take a look at Isolated EPGs. By default, endpoints within the same endpoint group are free to communicate with each. However, there are use-cases where you might want to group a common set of devices, allow them to communicate to an restricted set of services, but not allow them to communicate … More CPOC Series: Segmentation in ACI using Isolated EPGs
