In which EPG is the consumer interface of an L4-L7 device placed?
In the context of the ACI (Application Centric Infrastructure) architecture, an EPG (Endpoint Group) represents a collection of endpoints that have similar network requirements, such as security policies, QoS, and routing policies.
An L4-L7 device refers to a layer 4 to layer 7 service device, such as a firewall, load balancer, or IDS/IPS. These devices are typically placed between the consumer and provider EPGs to provide additional services to traffic flowing between the EPGs.
The consumer interface of an L4-L7 device is where traffic from the consumer EPG enters the device and where traffic destined for the consumer EPG exits the device. Therefore, the correct answer is A) consumer EPG.
The consumer EPG is the EPG where the endpoint initiating the traffic resides. The provider EPG is the EPG where the endpoint receiving the traffic resides. The shadow consumer EPG and shadow provider EPG are used in a different context, such as when implementing service graphs.
It's important to note that the placement of the L4-L7 device is determined by the service graph, which specifies the sequence of service nodes that traffic must traverse. The service graph can be applied to either the consumer EPG or the provider EPG, depending on the requirements of the deployment.
