This topic describes the `exported-services` configuration entry type. The `exported-services` configuration entry enables Consul to export service instances to other admin partitions from a single file. This enables your services to be networked across admin partitions. See [Admin Partitions](/docs/enterprise/admin-partitions) for additional information.

## Introduction ## Introduction
You can configure Consul to export services contained in an admin partition to one or more additional partitions by declaring the `exported-services` configuration entry in the `kind` field. This enables you to route traffic between services in different clusters that share a single set of Consul servers. You can configure Consul to export services contained in an admin partition to one or more additional partitions by declaring the `exported-services` configuration entry in the `kind` field. This enables you to route traffic between services in different clusters that share a single set of Consul servers.
You can configure the settings defined in the `exported-services` configuration entry to apply to all namespaces and federated datacenters. You can configure the settings defined in the `exported-services` configuration entry to apply to all namespaces and federated datacenters.
## Requirements ## Requirements
* A Consul Enterprise binary - A Consul Enterprise binary
* A partition that corresponds to the configuration entry. As in, the exported services config entry for partition "frontend" requires that the "frontend" partition exists - A corresponding partition that the configuration entry can export to. For example, the `exported-services` configuration entry for a partition named `frontend` requires an existing `frontend` partition.
## Usage ## Usage

## Example ## Example
The following example configures the agent to export the `billing` service from the `default` namespace of the `finance` admin partition to the `frontend` and `backend` partitions. Additionally, all services in all namespaces within the `finance` partition will be exported to the `monitoring` partition.
