CCN connects a VPC with another or with IDCs. This document introduces how to use CCN to interconnect VPCs in Guangzhou and Shanghai regions under the same account.
When creating a CCN instance, you can select either of the billing mode as needed: monthly subscription or monthly 95th percentile pay-as-you-go. The instance creation varies by the billing mode, as shown below:
This document guides you through how to interconnect a VPC in Guangzhou with a VPC in Shanghai under the same account.
You have created VPCs, subnets and CVMs in Shanghai and Guangzhou regions. The two subnets have no duplicate IP ranges, and CVMs reside in the subnets. For the step-by-step instructions, see Building Up a IPv4 VPC.
Log in to the Virtual Private Cloud Console.
Click Cloud Connect Network in the left sidebar to go to the CCN page, and then click +New.
In the Create CCN instance dialog box, complete the following configurations, and click OK.
|Name||-||Name of the CCN instance.|
|Billing Mode||Monthly subscription||Its unit price is about 20% lower than that of monthly 95th percentile billing. It's applicable to business with stable bandwidth needs.|
|Monthly 95th percentile||Bill the actual bandwidth usage of the current month on 95th percentile basis. It's applicable to business with fluctuating bandwidth demands.|
|Service Quality||Platinum||It’s ideal for key businesses that require extremely high communication quality. Gold service is suitable for businesses that require high communication quality, such as payment and game acceleration./td>|
|Gold||It’s suitable for businesses that require transmission of key business data, such as enterprise business data and ERP.|
|Silver||It’s suitable for cost-sensitive and jitter-insensitive businesses that require high security./td>|
|Speed Limit Mode||Region outbound speed limit||The overall outbound bandwidth limit from one region to another.|
|Inter-region speed limit||It’s the total bandwidth limit for traffic from a certain region to other regions. A monthly subscription CCN instance only supports the inter-region speed limit.|
|Associate with Instance||-||The options include VPC, Direct Connect Gateway, BM Virtual Private Cloud, and VPN Gateway. In this example, we choose to associate with VPC in the Shanghai region.|
Step 2: associate a network instance
To associate a VPC in the Guangzhou region with CCN, do as follows:
If you need to associate another network instance, click Add.
Step 3: check the route table
Check and confirm that routing policies of each subnet in the VPC associated with the CCN take effect. Any IP range conflicts between associated network instances will invalidate routes.
##Step 4: configure the bandwidth
-Purchasing bandwidth in both regions (only for monthly subscription CCN instances)
For monthly subscription CCN instances, bandwidth of 10 Kbps or less is free of charge in any region. If you need a higher bandwidth, purchase it according to regions.
The default bandwidth cap is 1 Gbps. If you want to increase the bandwidth, submit a ticket.
Communications between CCN instances may incur fees. For pricing details, see Pricing.
Log in to a CVM in Shanghai region, and run the
ping <IP address> to connect the CVM in Guangzhou region. If the following result appears, the two CVMs are successfully connected.
