 Mesh gateways enable the following scenarios:
 
-* **Federate multiple datacenters across a WAN**. Since Consul 1.8.0, mesh gateways can forward gossip and RPC traffic between Consul servers. See [WAN federation via mesh gateways](/docs/connect/gateways/wan-federation-via-mesh-gateways) for additional information. 
-* **Service-to-service communication across datacenters**. Refer to [Enabling Service-to-service Traffic Accross Datacenters](/docs/connect/gateways/mesh-gateway/service-to-service-traffic-datacenters) for additional information. 
-* **Service-to-service communication across admin partitions**. Since Consul 1.11.0, you can create administrative boundaries for single Consul deployements called "admin partitions". You can use mesh gateways to facilitate cross-partition communication. Refer to [Enabling Service-to-service Traffic Accross Admin Partitions](/docs/connect/gateways/mesh-gateway/service-to-service-traffic-partitions) for additional information.
