MCR Connections to Oracle Cloud Infrastructure using FastConnect

Transcription

1 MCR Oracle via FastConnect (OCI) 1 MCR Oracle via FastConnect (OCI) MCR Connections to Oracle Cloud Infrastructure using FastConnect To connect to FastConnect using MCR, you will need an Oracle Cloud ID (OCID) obtained via the Oracle Console. Creating a VXC to Oracle OCI via FastConnect from an MCR is a straightforward process via the Portal. Follow the steps below to establish a private connection to your Oracle Virtual Cloud Network (VCN). Before starting here are some key Oracle terms to understand: Compartments Compartments help you organize resources to make it easier to control access to them. Your root compartment is created for you by Oracle when your tenancy is provisioned. An administrator can create more compartments in the root compartment and then add the access rules to control which users can take action in them. At the time you create a resource, such as a cloud network, you choose which compartment to create it in. Once you create a resource, you cannot move it to another compartment. Virtual Cloud Network (VCN) A Virtual Cloud Network (VCN) is a customizable and private network in Oracle Cloud Infrastructure. Just like a traditional data center network, the VCN provides you with complete control over your network environment. This includes assigning your own private IP address space, creating subnets, route tables and configuring stateful firewalls. A single tenant can have multiple VCNs, thereby providing grouping and isolation of related resources. Dynamic Routing Gateway (DRG) A Dynamic Routing Gateway is a virtual edge router attached to your VCN that is necessary for private peering. The DRG is a single point of entry for private traffic coming in to your VCN. After creating the DRG, you must attach it to your VCN and add a route for the DRG in the VCN s route table to enable traffic flow. Virtual Circuit An isolated network path that runs over one or more physical network connections to provide a single, logical connection between the edge of your existing network and Oracle Cloud Infrastructure. Virtual Circuit Types

The connection is via a DRG you attach to your VCN Public Virtual Circuit Regional Oracle Cloud Infrastructure public IPv4 addresses are advertised (for example, for object storage). You also provide public IP prefixes that you want to advertise. Oracle Cloud Identifier (OCID) An Oracle-assigned unique ID called an Oracle Cloud Identifier (OCID). This ID is included as part of the resource s information in both the Console and API. When provisioning a FastConnect it s important to remember that a Dynamic Routing Gateway (DRG) is a standalone object. To use it, you must attach it to a Virtual Cloud Network (VCN). A VCN can be attached to only one DRG at a time, and vice versa. Oracle offers an SLA on its FastConnect connectivity, but in order to comply with this you must ensure to deploy two FastConnect virtual cross connects (VXCs) for redundancy. A common FastConnect deployment using a Megaport Cloud Router (MCR) might look like this: Pre-requisites for Private VCN connection In order to connect from an existing MCR to a VCN in Oracle you ll need to gather the following

3 MCR Oracle via FastConnect (OCI) 3 information: The Oracle OCID number. Oracle ASN # If you don t currently have an existing MCR, you may refer to our main Megaport Cloud Router (MCR) article to create one. Creating/confirming your Private ASN for FastConnect In order to connect MCR to your target Oracle VCN, login to the Oracle Console and complete the following: Create a new FastConnect Copy the OCID number Confirm the AS number. The AS# can be confirmed in the Oracle console by viewing the connection details of the new FastConnect. Completing an Oracle FastConnect request from MCR From the steps completed above, you now have enough information to create the VXC request in the Megaport portal to Oracle from the selected MCR. From the MCR choose +Connection and select the Cloud tile:

Select the appropriate destination port and select Next In the next screen, Connection Details (not shown), you will be asked the name of the connection (for display in the Megaport dashboard) and the rate limit. Note that the rate limit for the VXC will be capped at the maximum allowable as per that queried from the OCID. After entering the information select Next. The next screen, Connection Detail for MCR End(3) allows us to enter details that will be used to set up the peering session between the selected MCR and the Oracle edge device.

5 MCR Oracle via FastConnect (OCI) 5 For the IP address on this peering, the value /30 has been entered. Note that this is the second IP in the range as per the a.b.c.d+1 and will be the IP address that is configured on the MCR instance directed into the Layer 2 VXC instance facing Oracle in this example. Once this value has been accepted (by clicking the blue + symbol, where the trashcan icon is visible after the CIDR value) the next step is to move onto the BGP Connections panel and begin a BGP session configuration by once again pressing the blue + symbol. This will pull down the panel as shown above and for this example, we will be using the following values: Local ASN: ASN in this example however you may use another valid private (or public) value as required. Peer ASN: For Oracle via FastConnect this will be Ensure this value is correct. Local IP: Selected via a drop-down item, this will be populated from the IP addresses list entered above. Peer IP: This is a manually entered value and should be the CIDR notation of the IP address incremented +1 from that used above. BGP Authorization: This is not a mandatory field for Oracle connections as they traverse a private (non-internet) path. After these values have been entered (and checked) you may press Ok to save this BGP Connection 1 and proceed to the next step to accept the values, add to cart, and check-out the connection. Once the VXC connection is deployed successfully you will see it attached to the MCR on the Portal dashboard:

Note under the Details tab that both the service status (Layer 2) and BGP (Layer 3) are UP. You must set up both BGP sessions as separate VXCs for the Oracle FastConnect availability SLA to be valid. This may be configured on a single MCR or across two MCR instances depending on your HA requirements. To establish a separate BGP session create a new FastConnect on the Oracle Console and repeat the steps in the Megaport portal.
