# Configure Static and Dynamic Routes for a Cloud Router

The DynamicLink Cloud Router supports both static and dynamic routing so you can control how traffic is forwarded across your network.

* Static routes are manually defined.
  * Ideal for small, secure networks.
  * Predictable and efficient with resources.
  * Requires manual updates.
* Dynamic routes are learned automatically from routing protocols (in DynamicLink, we use BGP).
  * Ideal for large, changing networks.
  * Scalable and automatic failover.
  * Higher bandwidth usage and complexity.

You can configure routing from **Network > Cloud Router > Routes**.

## Add static routes

Static routes define a fixed path to a destination network. Use them when you need a specific next-hop or interface.

Next to **Routes > Static Routes**, click **Add**.

Complete the following fields:

| Field           | Description                                                                                                                                                                   |
| --------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Destination** | IP prefix to reach (IPv4 or IPv6), e.g. `192.168.1.0/24` or `10.0.0.0/8`                                                                                                      |
| **Type**        | **IP Address** for a normal next-hop route. <br /><br />**Interface** for a route to an interface. This is only supported for **IPSec** interfaces.                           |
| **Distance**    | Route distance (priority) for the route. By default, this is `1`. <br /><br /> Set a higher distance to make the route less desirable, for example to make it a backup route. |
| **Description** | Optional note for this route.                                                                                                                                                 |

Click **Add** to save.

## Dynamic routes (BGP)

Dynamic routes are learned from BGP neighbors (e.g. cloud gateways, data centers, or other networks). You do not "add" dynamic routes manually; you configure BGP and the Cloud Router learns and displays them.

For more information, see [Configure BGP for the Cloud Router](cloud-router-bgp).

<Note>
  If dynamic routes are missing:

  * Confirm the **BGP session** is up (neighbor status in the BGP tab).
  * Confirm the neighbor is **advertising** the expected prefixes (check Sent/Received in AWS, Azure, or your peer).
  * Review **route filters** and policies that might block or filter advertisements.
</Note>

## Route selection and precedence

When several routes exist to the same destination, the Cloud Router typically:

1. Prefers **static** over **dynamic** routes.
2. Uses **longest prefix match** (more specific prefix wins).
3. Uses **distance/metric** to choose among same-type routes.
