After you configure your Google Cloud resources, configure your Oracle
Cloud Infrastructure (OCI) resources.
Create a VCN
Create a virtual cloud network (VCN) that's in the same region and
tenancy as your FastConnect ports.
Console
Sign in to the OCI console.
Make sure that the Regions list shows the region where your
FastConnect port is located.
In the menu menu, select
Networking > Virtual cloud networks.
Click Create VCN.
Fill in the required fields, and then define at least one IPv4
CIDR block.
Click Create VCN.
Create a subnet
In your VCN, create a subnet.
Console
If you don't already have it displayed, navigate to the VCN that you
just created.
Click Add subnet.
Fill in the required fields, and then define at least one IPv4
CIDR block.
Click Create Subnet.
Create a DRG and attach it to your VCN
A Dynamic Routing Gateway (DRG) is a virtual router. Create a
DRG and attach it to your VCN.
Console
In the menu menu, select
Networking. In the Customer connectivity section, select
Dynamic routing gateway.
Click Create Dynamic Routing Gateway.
Enter a name.
Click Create Dynamic Routing Gateway.
OCI displays a page that represents the DRG; you might have to wait a
few minutes for the system to provision the resource. While it does so,
the controls on the page are disabled. When the controls become active,
click Create Virtual Cloud Network Attachment.
Enter an attachment name.
Select the VCN network that you created previously.
Click Create Virtual Cloud Network Attachment.
Create a private virtual circuit
For each of your FastConnect resources, create a private virtual circuit.
As part of this process, you configure a Border Gateway Protocol (BGP) session.
Complete the following steps twice. The first time, use the values that you
set for your primary VLAN attachment. The second time, use the values from
your redundant attachment.
Console
In the menu menu, select
Networking. In the Customer connectivity section, select
FastConnect.
Click the name of your FastConnect resource.
Click Virtual circuits. The page updates to include additional
options.
Click Add virtual circuit.
Fill out the Create virtual circuit form:
Enter a name for the circuit.
Select the Private virtual circuit box.
Select the DRG that you created previously.
In the Provisioned bandwidth field, enter the
capacity that you chose for your Google Cloud VLAN attachment.
In the VLAN field, enter the same VLAN ID that you chose for your
Google Cloud VLAN attachment.
In the Customer BGP IPv4 address field, enter the value from the
Cloud Router BGP IP field on your Google Cloud VLAN
attachment.
In the Oracle BGP IPv4 address field, enter the value from the
BGP Peer IP field on your Google Cloud VLAN
attachment.
In the Customer BGP ASN field, enter the value of your
Google Cloud Router ASN.
If you configured MD5 authentication on the
Cloud Router, select Use a BGP MD5 authentication key,
and enter your key.
Optional: Adjust the MTU from the default setting of 1500.
Click Create.
After you create each circuit, you see the corresponding BGP session.
