# Enabling Peering Control Plane Traffic
In addition to [service-to-service traffic routing](/consul/docs/connect/cluster-peering/usage/establish-cluster-peering),
we recommend routing control plane traffic between cluster peers through mesh gateways
to simplfy networking requirements.
This topic describes how to configure a mesh gateway to route control plane traffic between Consul clusters that share a peer connection. For information about routing service traffic between cluster peers through a mesh gateway, refer to [Enabling Service-to-service Traffic Across Admin Partitions](/consul/docs/connect/gateways/mesh-gateway/service-to-service-traffic-partitions).
Control plane traffic between cluster peers includes
the initial secret handshake and the bi-directional stream replicating peering data.

In addition to the [ACL Configuration](/consul/docs/connect/cluster-peering/tech-specs#acl-specifications) necessary for service-to-service traffic, mesh gateways that route peering control plane traffic must be granted `peering:read` access to all peerings.
This access allows the mesh gateway to list all peerings in a Consul cluster and generate unique routing per peered datacenter.
