Replication across GCP regions - Linux

Last published : Jun 10, 2026
In this scenario, replication is set up across zones that are configured in different regions and VPC peering is used to connect the networks.
  • Two VPCs with valid CIDR blocks (for example, 10.30.0.0/16 and 10.60.0.0/16 respectively) that are located in two different regions.
  • The primary instance belongs to Zone1 of region A and the secondary instance belongs to Zone1 of region B.
  • InfoScale instances in each zone.
  • Set up VPC peering between the two regions.
  • Elastic IP addresses (EIP) to connect the two VPN instances
  • Private IP addresses used for replication in standalone environments
OR
Virtual private IP addresses used for replication in clustered environments

Setting up replication across regions
Perform the steps in the following procedure to set up replication across regions.
To set up replication across regions
  1. Create two VPCs with valid CIDR blocks in different regions, for example, 10.30.0.0/16 and 10.60.0.0/16 respectively.
  2. Create the primary site VM instance.
  3. Create the secondary site VM instance.
  4. Set up replication between the instances using the private IP address or virtual private IP address.
For instructions on setting up replication, refer to the InfoScale Replication Administrator's Guide - Linux.
  1. Verify the status of replication.
# vradmin -g dg_name repstatus rvg_name
Ensure that the replication status shows:
Replication status: replicating (connected)
