Step 3: Create a Virtual Interface

Scenarios

After the connection and the gateway are ready, you need to create a virtual interface so that your network can access the VPC.

Procedure

1. Log in to the management console.
2. On the console homepage, click in the upper left corner and select the desired region and project.
3. Hover on to display Service List and choose Networking > Direct Connect.
4. In the navigation pane on the left, choose Direct Connect > Virtual Interfaces.
5. Click Create Virtual Interface.
   Configure the parameters based on Table 1.

   Table 1 Parameters for creating a virtual interface

   Parameter	Description
   Region	Specifies the region where the connection resides. You can also change the region in the upper left corner of the console.
   Name	Specifies the virtual interface name. The name can contain 1 to 64 characters.
   Virtual Interface Priority	Specifies whether the virtual interface will be used prior to other virtual interfaces. There are two options: Preferred and Standard. If multiple virtual interfaces are associated with one Direct Connect device, load is balanced among virtual interfaces with the same priority, while virtual interfaces with different priorities are working in active/standby pairs.
   Connection	Specifies the connection you can use to connect your on-premises network to Huawei Cloud.
   Virtual Gateway	Specifies the virtual gateway that the virtual interface connects to.
   VLAN	Specifies the ID of the VLAN for the virtual interface. You need to configure the VLAN if you create a connection on your own. The VLAN for a hosted connection will be allocated by the carrier or partner. You do not need to configure the VLAN.
   Bandwidth	Specifies the bandwidth that can be used by the virtual interface, in Mbit/s. The bandwidth cannot exceed that of the connection.
   Enable Rate Limiting	Limits the highest bandwidth that can be used by the virtual interface. If this option is enabled, the rate limit gradients are as follows: If the bandwidth is less than or equal to 100 Mbit/s, the rate limit gradient is 10 Mbit/s. If the bandwidth is greater than 100 Mbit/s but is less than or equal to 1,000 Mbit/s, the rate limit gradient is 100 Mbit/s. If the bandwidth is greater than 1,000 Mbit/s but is less than or equal to 100 Gbit/s, the rate limit gradient is 1 Gbit/s. If the bandwidth is greater than 100 Gbit/s, the rate limit gradient is 10 Gbit/s. For example, if the bandwidth is 52 Mbit/s, the actual rate limit is 60 Mbit/s. If the bandwidth is 115 Mbit/s, the actual rate limit is 200 Mbit/s. NOTE: Bandwidth limiting of virtual interfaces is being and will be launched in each region. You can view the regions where the option is rolled out on the management console.
   Enterprise Project	Provides a cloud resource management mode where cloud resources and members are centrally managed by project.
   Local Gateway	Specifies the gateway on the Huawei Cloud network.
   Remote Gateway	Specifies the gateway on your on-premises network. The remote gateway must be in the same IP address range as the local gateway. Generally, a subnet with a 30-bit mask is recommended.
   Remote Subnet	Specifies the subnets and masks of your on-premises network. If there are multiple subnets, use commas (,) to separate them.
   Routing Mode	Specifies whether static routing or dynamic routing is used to route traffic between your on-premises network and the cloud network. If there are or will be two or more connections, select BGP routing to achieve higher availability.
   BGP ASN	Specifies the autonomous system number (ASN) of the BGP peer. This parameter is required when BGP routing is selected.
   BGP MD5 Authentication Key	Specifies the password used to authenticate the BGP peer using MD5. This parameter is mandatory when BGP routing is selected, and the parameter values on both gateways must be the same. The key contains 8 to 255 characters and must contain at least two types of the following characters: Uppercase letters Lowercase letters Digits Special characters ~!, .:;-_"(){}[]/@#$ %^&*+\|=
   Description	Provides supplementary information about the virtual interface.

   

   When you configure the local and remote gateways, note the following:

   • The local gateway is used by Huawei Cloud for connecting to your equipment room. After you configure Local Gateway on the console, the configuration will be automatically delivered to the gateway used by Huawei Cloud.
   • The remote gateway is used by your equipment room for connecting to Huawei Cloud. After you configure Remote Gateway on the console, you also need to configure the gateway deployed in your equipment room.
   • The local and remote gateways must use the same CIDR block and cannot conflict with service IP addresses on the network.
6. Click Create Now.

   Ensure that the virtual interface is in the Normal state.

7. Ping the IP address of a server in the VPC from your on-premises data center to check network connectivity.
