Create and manage a router

Cloud Router enables you to dynamically exchange routes between networks. You can find the list of routers in networking settings, on the Routers page.

Create a router

A router can be created in two ways:

• Manually on the Routers page as documented in the following section.

• After you create a network, a new router is automatically created in the cloud to enable traffic routing. You can configure automatically created routers using the same settings available for manually created routers.

Create a router manually

1. In the Gcore Customer Portal, navigate to Cloud > Networking.

2. Go to the Routers page and click Create router.

3. Select the network and subnetwork to configure routing. If necessary, you can add multiple subnetworks by clicking on Add Subnet. For more information about creating and configuring a network and subnetwork, refer to our Networking guide.

4. (Optional) Turn on the Enable SNAT toggle if you need access to the external network. A separate public IP address is announced for a router with access to an external network.

5. In the Static Routes section, you can specify the routing scheme. Provide the destination prefix and the address of the next hop. To add the next route, click the Add Route button.

6. Give your router a name and save the configuration by clicking Create Router.

Manage routers

To manage routers:

1. Open the Routers page in the Gcore Customer Portal.

2. Click the router name to access its settings. Alternatively, click the three-dot icon next to the router you want to manage and then select Overview.

3. On the router overview page, you can find general information such as router ID, whether there is a SNAT for accessing the external network, creation dates, and external IPs. Here you can also configure and add new subnetworks as well as update static routes.

Configure a subnetwork

In the Subnets section, you can manage the list of subnets added to the router, add new subnets, and delete the existing ones.

When creating a subnetwork, pay attention to the supported CIDR ranges:

• 10.0.0.0/8
• 172.16.0.0/12
• 192.168.0.0/16
• fc00::/7

The specified CIDR ranges must align with the destinations configured in your static routes.

Configure static routes

In the Static Routes section, you can update the destination and nexthop of your routes, add new ones, or remove static routes from the router.
