# Gateway ratios

For every **one Border Gateway** deployed, up to **20 Mesh Gateways** can be deployed, depending on the Site's topology. However, as Mesh Gateways act as repeaters, any number of Mesh Gateways can be deployed on a Site.

Ensure each Mesh Gateway can communicate with at least two other Mesh Gateways. This ensures a reliable Mesh Network in the forest.

{% hint style="info" %}
Additional Border Gateways can be deployed as a backup for the Mesh Network.
{% endhint %}

In the following figure, one Border Gateway (plus a backup Border Gateway) receives communication from 20 Mesh Gateways. Note the connectivity paths between Mesh Gateways. With a few exceptions, each Mesh Gateway connects with at least two other Mesh Gateways.

When using the [Planning tool](/dryad-documentation/site-planning/coverage-estimation.md), the **Connectivity tool** helps to ensure Mesh Gateways have multiple paths to the Border Gateway.
