Peer a VPC network

Virtual Private Cloud network peerings define network connectivity between Google Cloud VMware Engine networks, Google VPCs, and other services. This document describes how to create a VPC network peering between a VMware Engine network and another network.

Note: VPC peering is only available for Standard VMware Engine networks. For Legacy VMware Engine networks see, Set up private connections.

Types of peerings

The following types of peerings are supported:

• Standard: A connection from the VMware Engine network to a VPC within the same or different project.
• Shared VPC: A VMware Engine network can peer with Shared VPC. Use standard peering when peering with Shared VPC.
• VMware Engine network: A connection between VMware Engine networks within the same or different project.
• Private services access: A connection used for establishing private services access, for example, to peer with services such as Cloud SQL.
• NetApp Cloud Volumes: A connection to NetApp Cloud Volumes.
• Dell PowerScale: A connection to Dell PowerScale Storage.
• Third-party service: A connection to third-party services. Most third-party services require manual setup of reverse peering on the VPC network associated with the third-party service.

Note: A peering configuration establishes the intent to connect to another VPC network. Your VMware Engine network and the other network are not connected until each one has a peering configuration for the other.

If you are peering to a network in a different project, you must complete creation of the VPC network peering in both projects by completing the peering in the project where the VMware Engine network and private cloud are located. To do this, follow these steps:

1. Switch to the project of the VPC you are trying to peer with.
2. In the VPC target project, return to the VMware Engine VPC Network Peerings and select to peer a VMware Engine network in another project.
3. Specify the project ID and VMware Engine network name, and then peer with the VPC you want to complete the bi-directional peering.

Create a VPC network peering with VPC

To create a new VPC network peering with VPC using the Google Cloud console, Google Cloud CLI or Google Cloud VMware Engine, do the following. The following examples creates a new VPC network peering a VMware Engine network ven1 and a VPC network vpc.

Console

To create a new VPC network peering with another VMware Engine using the Google Cloud console, do the following:

1. In the Google Cloud console, go to the VPC Network peerings page.

   Go to VPC Network peerings

2. Click Create.

3. In the Name field, provide a name for your network peering.

4. In the VMware Engine network section, specify the VMware Engine network you want to peer.

5. In the Peering section, select VMware Engine network as the Peering type.

7. Optional: In the Route exchange section, choose the required route exchange behavior for the network peering.

8. Click Create.

gcloud

To create a new VPC network peering with another VMware Engine using the Google Cloud CLI, use the gcloud vmware network-peerings create command:

gcloud vmware network-peerings create NETWORK_PEERING_ID \
  --description="DESCRIPTION" \
  --peer-network-type=VMWARE_ENGINE_NETWORK \
  --peer-network=VMWARE_NETWORK_ID_1 \
  --vmware-engine-network=VMWARE_NETWORK_ID_2

Replace the following:

• NETWORK_PEERING_ID: a name for your network peering. For example peering2.
• DESCRIPTION: a description for this request, such as "Peering two VMware Engine networks".
• VMWARE_NETWORK_ID_1: the network ID for one VMware Engine network. For example, ven1.
• VMWARE_NETWORK_ID_2: the network ID for the other VMware Engine network. For example, ven2.

API

To create a new VPC network peering with another VMware Engine using the VMware Engine API, make a POST request:

POST "https://vmwareengine.googleapis.com/v1/projects/PROJECT_ID/locations/global/networkPeerings?network_peering_id=NETWORK_PEERING_ID" -d '{
"vmware_engine_network": "projects/PROJECT_ID/locations/global/vmwareEngineNetworks/VMWARE_NETWORK_ID_1",
  "description": "DESCRIPTION",
  "peer_network_type": "VMWARE_ENGINE_NETWORK",
  "peer_network": "projects/PROJECT_ID/global/networks/vmwareEngineNetworks/VMWARE_NETWORK_ID_2"

Routing limits

The maximum number of routes that a private cloud can receive is 200. For example, those routes can come from on-premises networks, peered VPC networks, and other private clouds in the same VPC network. This route limit corresponds to the Cloud Router maximum number of custom route advertisements per BGP session limit.

In a given region, you can advertise at most 250 unique routes from VMware Engine to your VPC network using private services access. For example, those unique routes include private cloud management IP address ranges, NSX-T workload network segments, and HCX internal IP address ranges. This route limit includes all private clouds in the region and corresponds to the Cloud Router learned route limit.

For information about routing limits, see Cloud Router Quotas and limits.
