1.1 What is peering?

The Peering service

Peering lets you connect two active VPC Networks that are in the same region and associated with the same project.

Benefits of creating a peering

Reduced latency: creating a direct link significantly lowers communication times between the two networks.
Increased security: traffic between the two connected networks does not traverse the public Internet.
Simplified management: the direct link does not require complex tunneling configurations.

Steps to creating a peering

Enable the interconnection between two VPC Networks (peering).
Check the requirements.
Configure the peering routes to connect the subnets of the VPC Networks.

Peering status

Peering status	Satus description	Action
Creation in progress	Peering between the two VPC Networks is being created.	Wait for the creation to finish.
Active	Peering between the two VPC Networks has been created.	You must create the peering routes; without them the service will not work.
Connected	Peering routes have been created and associated with the peering.	Check that the interconnection between the two VPC Networks is working.

SOURCE / DESTINATION

When creating a peering you must specify the two VPC Networks involved, referred to as:

SOURCE - the first selected VPC Network, from which peering creation is initiated;
DESTINATION - the VPC Network you want to connect to the first VPC Network (SOURCE).

The distinction between SOURCE and DESTINATION is purely formal and applies only during peering creation. Once established, the peering is bidirectional and can be managed from either of the VPC Networks involved.

Peering Route

Peering routes are routing rules that allow traffic between two VPC Networks connected via peering. These rules define which subnets can communicate over the link.

To ensure peering works correctly, make sure you have met the requirements for creating peering routes.
