Setting Up a Connection Using Direct Cross Connects

Cross Connect represents the physical cable that connects your existing network to Oracle in the FastConnect location. Complete the following tasks to set up connection using Direct Cross Connects. This topic is not relevant if you are setting up a connection through an Oracle FastConnect Partner.

• Creating a Cross Connect

• Forwarding Letter of Authorization

Prerequisites to Connect Using Direct Cross Connects

• You are responsible for provisioning the physical connectivity to the Oracle routers through a network service provider or carrier of your choice. Your network service provider must be capable of connecting to the Oracle routers over single-mode fiber. If your infrastructure is colocated with the Oracle data center, order cross connects from the data center provider.

• You need to provide one /30 or /31 IP subnet for every virtual circuit that you create. You can provide a public or private IP subnet. If you are providing a public IP subnet, these IP subnets should be owned by you and registered in an Internet Routing Registry (IRR) or Regional Internet Registry (RIR). Work with your Internet service provider or with your RIR to obtain IPv4 address allocation.

• You require a valid 2-byte or 4-byte Autonomous System Number (ASN) that is registered to you for establishing the peering session. Work with your Internet service provider or one of the registries to obtain an ASN.

  Note:

  If you do not have a registered public ASN, you can use private ASNs or use the fixed ASN provided by Oracle for configuring the network. You cannot use 64555 as ASN for private peering as it is reserved for internal routing on Oracle.

• MD5 hash support is optional.

• If you are setting up a public peering session, you are responsible for NATing your private IP addresses and you can advertise only public IP addresses to Oracle over the public peering session.

• You are responsible for setting up the physical connectivity to the demarcation point provided in the letter of authorization.

Creating a Cross Connect

Create a cross connect to establish a physical connection between the routers in your network and Oracle routers. You should create only one cross connect for every router in your network.

Prerequisites

• To complete this task, you must have the Compute_Operations role. If this role isn’t assigned to you or you’re not sure, then ask your system administrator to ensure that the role is assigned to you in Oracle Cloud Infrastructure Classic Console. See Modifying User Roles in Managing and Monitoring Oracle Cloud.

Procedure

1. Sign in to the FastConnect Classic console. If your domain spans multiple sites, select the appropriate site. To change the site, click the Site menu near the top of the page.
2. Click the Network tab.
3. In the Network drop-down list, expand FastConnect, and then click Cross Connects.
4. Click Create Cross Connect.
5. Select or enter the following information:
   • Name: Enter a name for the cross connect.
   • Port speed: Select the appropriate port speed based on your business requirement.
   • Make this Cross Connect redundant from: If you are creating a secondary cross connect, select the primary cross connect that you have created. This ensures that the primary and secondary cross connects are mapped to unique routers. If you don’t specify a value while creating a secondary cross connect, both primary and secondary cross connects are mapped to the same router and redundancy is not achieved at the router level. If you are creating a primary cross connect, leave this field empty.
   • Your Circuit ID: Enter the circuit ID, if you have assigned one for your network router. This helps you to identify the cross connect that maps to a router in your network. This is useful when you want to troubleshoot.
6. Click Create.
   The Confirm Create Cross Connect Details page appears.
7. Check if the details provided are correct, make a note of the next steps that you have to perform, and then click Confirm.

After creating a cross connect to the primary port, repeat this task to create a redundant cross connect to a redundant router in your network to achieve end-to-end redundancy from your network edge. After creating both the cross connects, you can forward the letter of authorization. See Forwarding Letter of Authorization.

Forwarding Letter of Authorization

After creating a cross connect, you can view the letter of authorization which provides details that are required to set up a physical connection between your network routers and Oracle routers. You have to forward this letter to activate the cross connect by setting up the physical connection.

Prerequisites

Before forwarding the letter of authorization, ensure that you meet the following prerequisites.

• If your data center is not colocated with the Oracle data center where your Oracle Cloud services are provisioned, contact your network service provider to order a private line from your premises to the Oracle data center. Identify a network service provider or carrier that can deliver an Ethernet private line from your premises to the Oracle edge routers. The service provider must be capable of terminating the circuit using single-mode fiber with LC connectors. The ports on Oracle routers are 1000Base-LX (1 Gbps) and 10GBASE-LR (10 Gbps). It is your responsibility to work with any network service provider or carrier of your choice to get the point-to-point Ethernet private line provisioned to the demarcation point as specified in the letter of authorization. If the network carrier is located in a different demarcation point in the cage, you must work with the network carrier to get the connection established from their demarcation point to the Oracle demarcation point.

  To achieve end-to-end redundancy from your network edge, you must order redundant circuits or lines from your network service provider along with separate cross connects to Oracle edge routers from redundant routers in your network.

• Ensure that the life cycle status of the cross connect is Provisioned.

• To complete this task, you must have the Compute_Monitor or Compute_Operations role. If this role isn’t assigned to you or you’re not sure, then ask your system administrator to ensure that the role is assigned to you in Oracle Cloud Infrastructure Classic Console. See Modifying User Roles in Managing and Monitoring Oracle Cloud.

Procedure

1. Sign in to the FastConnect Classic console. If your domain spans multiple sites, select the appropriate site. To change the site, click the Site menu near the top of the page.
2. Click the Network tab.
3. In the Network drop-down list, expand FastConnect, and then click Cross Connects.
4. Go to the cross connect for which you want to retrieve the letter of authorization. From the menu, select Letter of Authorization.
5. Copy the contents of the letter of authorization and forward it to [e-mail] to activate the cross connect. Additionally, forward the letter of authorization to the data center provider or network carrier of your choice.
   • If your data center is colocated with the Oracle data center, forward the letter of authorization to the data center provider.
   • If your data center is not colocated with the Oracle data center where your Oracle Cloud services are provisioned, forward the letter of authorization to the network carrier of your choice.

   Note:

   The LOA is valid only for a limited period. If you don’t establish a physical connection between your network routers and Oracle routers within this period, the LOA is revoked.

Oracle configures the routers. When the physical connection between your network routers and Oracle routers is set up and the configuration is complete, the Physical Status of the cross connect changes to Up and the Life Cycle Status is Provisioned. You can now create a virtual circuit. See Creating a Virtual Circuit.
