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	Create three enterprise routers with one in each region. Create a service VPC and its subnet in each region. Create an ECS in the subnet of the service VPC. Create a central network. When creating the central network, create a policy and add the enterprise routers in different regions to the policy. 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.
