What controls communication between EPGs?
Inter-EPG communication is controlled by contracts. EPGs (Endpoint Groups) in a Cisco ACI (Application Centric Infrastructure) environment communicate with each other through defined contracts. These contracts specify the rules and policies for communication, allowing or denying traffic between different EPGs.
Id say: B. Inter-EPG communication is controlled by contracts.
In Cisco ACI, contracts are the primary mechanism used to control communication between Endpoint Groups (EPGs). By default, EPGs in ACI cannot communicate with each other unless a contract is explicitly defined or the VRF is set to "unenforced" mode. Contracts specify the type of traffic (e.g., protocols, ports) that is allowed or denied between EPGs, providing a highly granular and secure method of controlling communication.
