Lesson 3: How to Configure Inter-Tenant Communication with Contract Interface Import
In lesson three of this ACI training series, Daniel Pita demonstrates how to Configure Inter-Tenant Communication with Contract Interface Import. The following additional informational resources are provided in this lesson.
- In Cisco ACI, a tenant is a unit of isolation from a policy perspective, but it does not represent a private network. Tenants can represent a customer in a service provider setting, an organization or domain in an enterprise setting, or just a convenient grouping of policies. Cisco ACI tenants can contain multiple private networks (VRF instances).
- Contracts are rules that specify what and how communication in a network is allowed. Contracts specify how communications between EPGs take place. Contract scope can be limited to the EPGs in an application profile, a tenant, a VRF, or the entire fabric.
- EPG is a logical entity that contains a collection of physical or virtual network endpoints. In Cisco ACI, endpoints are devices connected to the network directly or indirectly. They have an address (identity), a location, attributes (e.g., version, patch level), and can be physical or virtual. Endpoint examples include servers, virtual machines, storage, or clients on the Internet.
