Process of Connecting VPCs Across Regions Using Enterprise Router and Central Network

Table 1 describes the process of enabling VPCs in different regions to communicate with each other through enterprise routers and a central network.

Table 1 Steps for connecting VPCs across regions

No.

Step

Description

1

Creating Cloud Resources
  1. Create three enterprise routers with one in each region.
  2. Create a service VPC and its subnet in each region.
  3. Create an ECS in the subnet of the service VPC.
  4. Create a central network. When creating the central network, create a policy and add the enterprise routers in different regions to the policy.
  5. Purchase three global connection bandwidths to connect networks in different regions.

2

Creating VPC Attachments for Enterprise Routers

Create a VPC attachment to each enterprise router.

3

Assigning Cross-Site Connection Bandwidths

Assign cross-site connection bandwidths on the central network based on service requirements.

4

Verifying Network Connectivity

Log in to an ECS and run the ping command to verify the network connectivity.
