Binding a Premium BGP EIP to an ECS to Enable Internet Access

Scenarios

Premium BGP provides fast and high-quality public network lines between Chinese mainland and the rest of the world. BGP is used to interconnect with lines of multiple mainstream carriers. Public network connections that feature low latency and high quality are directly established between Chinese mainland and CN-Hong Kong.

• Bandwidths of the premium BGP type are available only in CN-Hong Kong.
• Premium BGP EIPs can be billed on a yearly/monthly or pay-per-use basis.
• Premium BGP bandwidths do not support shared data packages and bandwidth add-on packages.

Architecture

This document takes Figure 1 as an example. Suppose you deploy your web application on an ECS in CN-Hong Kong and bind a premium BGP EIP to this ECS. And then users from the Chinese mainland can access your application faster through the optimal path.

Figure 1 Binding a premium BGP EIP to an ECS

In this example, ECS-A is deployed in CN-Hong Kong, and EIP-A is a premium BGP EIP in CN-Hong Kong. To bind EIP-A to ECS-A, you need to:

1. Assign a premium BGP EIP.
2. Bind an EIP to an ECS.

Constraints

• Each EIP can be bound to only one cloud resource and both should be in the same region.
• An EIP and its bound cloud resource can use different billing modes.

  For example, a yearly/monthly EIP can be bound to a pay-per-use ECS.

Step 1: Assign a Premium BGP EIP

1. Go to the Buy EIP page.
2. Set the parameters as prompted.
3. The values in Table 1 are only examples for your reference. You can modify them as required.

   Table 1 Parameter description

   Item	Parameter	Description	Example Value
   Basic Configuration	Billing Mode	You can select: Yearly/Monthly Pay-per-use	Yearly/Monthly
   Basic Configuration	Region	The region where your EIP is deployed. In this example, select CN-Hong Kong.	CN-Hong Kong
   Bandwidth Details	EIP Type	Premium BGP NOTE: Premium BGP is available only in CN-Hong Kong.	Premium BGP
   Bandwidth Details	Bandwidth (Mbit/s)	The bandwidth size in Mbit/s.	1
   Bandwidth Details	Bandwidth Name	The name of the bandwidth.	bandwidth
   DDoS Protection	DDoS Protection	Cloud Native Anti-DDoS Basic Cloud Native Anti-DDoS Basic provides up to a certain amount of DDoS mitigation capacity for free, for example, 500 Mbit/s. The actual thresholds are displayed on the console. If the attack to an EIP exceeds the threshold, the EIP will be blocked.	-
   EIP Details	EIP Name (Optional)	The EIP name.	EIP-A
   EIP Details	Enterprise Project	The enterprise project that the EIP belongs to. An enterprise project facilitates project-level management and grouping of cloud resources and users. The default project is default. For details about creating and managing enterprise projects, see the Enterprise Management User Guide.	default
   EIP Details	IPv6 EIP (Optional)	After the IPv6 EIP function is enabled, you will obtain both an IPv4 EIP and its corresponding IPv6 EIP. External IPv6 addresses can access cloud resources through this IPv6 EIP.	Enable
   EIP Details	Tag	The EIP tags. Each tag contains a key and value pair. NOTE: If your organization has created a tag policy for EIP, you need to add tags for EIP based on the tag policy. If a tag does not comply with the tagging rules, the creation may fail. Contact the organization administrator to learn details about the tag policy.	Key: Ipv4_key1 Value: 3005eip
   Monitoring	Monitoring	Used to monitor the EIP and enabled by default. You can use the management console or APIs provided by Cloud Eye to query the metrics and alarms generated for the EIP and bandwidth.	-
   Purchase Details	Required Duration	How long you will use your EIP. The duration must be specified if the Billing Mode is set to Yearly/Monthly.	1 month

5. Confirm the information and click Pay Now.
6. On the order page, click Confirm.

Step 2: Bind an EIP to an ECS

1. In the EIP list, locate the target EIP, and click Bind in the Operation column.
2. Select the ECS and bind the EIP to it.
   

   If the ECS has an EIP bound to it, unbind that EIP from the ECS first.

3. Click OK.
