Create a peering connection

An organization administrator can create peering connections for resources only in its organization.

 

You can set up peering connections between VPCs or classic networks when deployment mode selection is enabled or disabled.

• When deployment mode selection is disabled, you can create peering connections as follows:

• Create a peering connection between local subnets and peer subnets. Firewalls are enabled by default, and the firewall state is not configurable.

• Create a peering connection between two networks. Firewalls are disabled by default, and the firewall state is not configurable.

• When deployment mode selection is enabled, you can create peering connections as follows:

• In centralized deployment mode, create a peering connection between local subnets and peer subnets, and set the state of firewalls.

• In distributed deployment mode, create a peering connection between two networks. Firewalls are disabled by default, and the firewall state is not configurable.

Create a peering connection with deployment mode selection disabled

1. On the top navigation bar, click Cloud Services, and then select Peering Connections from the Network menu.

2. From the left navigation pane, select Advanced Settings > Peering Connection Settings.

3. Disable deployment mode selection.

4. From the left navigation pane, select Peering Connections.

5. Click Create.

6. Configure the peering connection parameters.

Table-1 Configuring peering connection parameters

Parameter		Description
Basic Info	Name	Enter a name for the peering connection.
Local Resource	Resource Type	Select VPC or router as the local network type.
	Local VPC/Local Router	Select a local VPC or a router of a local classic network.
	Local Subnets	Select the local subnets that require Layer 3 connectivity to the peer resources. If you do not select any subnets, you cannot select subnets when you edit the peering connection.
Peer Resource	Organization	Select the current organization or a different organization.
	Peer Organization	Select a peer organization. The peering connection is set up after an organization administrator of the peer organization accepts the peering connection request. This parameter is available if Other Organization is selected for the Organization parameter.
	Resource Type	Select VPC or router as the peer network type. Make sure the local and peer resource types are consistent.
	Peer VPC/Peer Router	Select a peer VPC or a router of a peer classic network.
	Peer Subnets	Select the peer subnets that require Layer 3 connectivity to the local resources. If you do not select any subnets, you cannot select subnets when you edit the peering connection.

If the peering connection is set up within an organization, the state of the peering connection is Accepted. If the peering connection is set up between two organizations, the state of the peering connection is Pending. The state will become accepted after the peering connection is accepted by the peer organization.

Create a peering connection with deployment mode selection enabled

With deployment mode selection enabled, you can set the state of firewalls and select whether to set up a peering connection between selected subnets.
