Creating a Dynamic Routing Gateway

On Compute Cloud@Customer, a DRG is the equivalent of a general purpose router. A DRG is used to connect a VCN to the data center's IP address space. The router is configured separately from the VCNs, at the compartment level and is not required to be in the same compartment as the VCN (but it typically is).

After the DRG is configured, the DRG can be attached to more than one VCN and, similar to a physical router, can be attached and detached at any time, although perhaps with traffic loss. Also like a physical router, even when attached to a VCN, the DRG must have route table rules to steer traffic to the on-premises data center network's IP address space.

Avoid entering confidential information in names and tags.

    1. In the Compute Cloud@Customer Console navigation menu, under Networking, click Dynamic Routing Gateways (DRGs).

    2. Click Create Dynamic Routing Gateway.

    3. Fill in the required information:

      • Name: Provide a name or description for the dynamic routing gateway. Avoid using any of the organization's confidential information.

      • Create in Compartment: Select the compartment in which to create the dynamic routing Gateway.

      • Tagging: (Optional) Add one or more tags to this resource. Tags can also be applied later. For more information about tagging resources, see Resource Tags.

    4. Click Create Dynamic Routing Gateway.

      The Dynamic Routing Gateway is now ready for the addition of DRG attachments. See Attaching VCNs to a Dynamic Routing Gateway.

  • Use the oci network drg create command and required parameters to create a dynamic routing gateway.

    oci network drg create [OPTIONS]

    For a complete list of CLI commands, flags, and options, see the Command Line Reference.

  • Use the CreateDrg operation to create a dynamic routing gateway.
