Obtaining the Peer Project ID of a VPC Peering Connection Scenarios If you create a VPC peering connection between two VPCs in different accounts, you can refer to this section to obtain the project ID of the region that the peer VPC resides. Procedure Log in to the management console
Using a VPC Peering Connection to Connect Two VPCs You can configure a VPC peering connection and set the destination of the routes added to VPC route tables to the peer VPC CIDR block. In this way, all resources in the two VPCs are connected. Table 1 shows example scenarios. Table
Which CIDR Blocks Are Available for the VPC Service? When creating a VPC, you need to specify an IPv4 CIDR block for it. Consider the following when selecting a CIDR block: Reserve enough IP addresses for subsequent service expansion. Avoid CIDR block conflicts. To enable communications
Setting Up an IPv4/IPv6 Dual-Stack Network in a VPC This topic describes how to create a VPC with both IPv4 and IPv6 CIDR blocks for an ECS to allow the ECS to have both IPv4 and IPv6 addresses. You can bind an EIP to the ECS and create a shared bandwidth to enable the ECS to communicate
Viewing the Traffic Between VPCs Connected by a VPC Peering Connection Solution Architecture In this example, a VPC peering connection Peer-AB is used to enable communications between two VPCs (VPC-A and VPC-B). If O&M engineers need to view the traffic between the two VPCs, you can
Using a VPC Peering Connection to Connect Subnets in Two VPCs You can configure a VPC peering connection and set the destination of the routes added to VPC route tables to the subnet CIDR block of the peer VPC. In this way, all resources in the VPC subnets are connected. Table 1 shows
Using a VPC Peering Connection to Connect ECSs in Two VPCs You can configure a VPC peering connection and set the destination of the routes added to VPC route tables to the private IP address of ECS in the peer VPC. In this way, the two ECSs are connected. To enable traffic forwarding
How Do I View My VPC Bills? VPC provides a wide range of cloud resources. Some are free, while some are not. Table 1 describes how these resources are billed. Table 1 VPC billing Service Resource VPC EIP Fixed bandwidth Add-on package VPC endpoint You can perform the following operations
Mirroring Inbound and Outbound TCP Traffic to a Network Interface in a Different VPC Solution Architecture To mirror inbound and outbound TCP traffic between a mirror source (network interface) and a given instance to a mirror target (network interface) in a VPC different from the
Creating a VPC Peering Connection to Connect Two VPCs in Different Accounts Scenarios Two VPCs from the same region cannot communicate with each other by default, but you can use a VPC peering connection to connect them. The following describes how to create a VPC peering connection
Extending a VPC CIDR Block Using a Secondary IPv4 CIDR Block Scenarios Generally, the number of IP addresses in a VPC CIDR block determines how many cloud resources that can be deployed in the VPC. If there are no sufficient IP addresses in the VPC CIDR block, you can add a secondary
Creating a VPC Peering Connection to Connect Two VPCs in the Same Account Scenarios Two VPCs from the same region cannot communicate with each other by default, but you can use a VPC peering connection to connect them. The following describes how to create a VPC peering connection
Can a VPC Peering Connection Connect VPCs in Different Regions? A VPC peering connection only can connect VPCs in the same region. A VPC peering connection can only connect VPCs in the same region. If your VPCs are in different regions, use Cloud Connect. Figure 1 shows an application
Why Is My VPC Still Being Billed After It Was Deleted? Symptom As shown in Figure 1, you deleted all VPCs under your account. However, there are still bills for VPC. Figure 1 VPC list Reasons In the Billing Center, on the By service type tab, click Virtual Private Cloud (VPC), and
Using a Third-Party Firewall to Scrub Traffic for VPCs Connected by VPC Peering Connections Application Scenario VPC allows you to configure and manage virtual networks. You can use security groups and network ACLs to control network access. You can also use third-party firewalls
How Many VPC Peering Connections Can I Create in an Account? To check how many VPC peering connections you can create in a region, you can go to the console. Number of VPC peering connections that you can create in each region between VPCs in the same account: subject to the actual
What Are the Differences Between the VPC Subnet API and the OpenStack Neutron Subnet API? Differences Subnet APIs are classified into VPC subnet APIs and subnet APIs. They can create, query, update, and delete subnets. The differences between the two are the meanings of the network
Why Does Communication Fail Between Two ECSs in the Same VPC or Packet Loss Occur When They Communicate? Symptom Two ECSs in the same VPC cannot communicate with each other or there is packet loss when they communicate. Troubleshooting The issues here are described in order of how
