This document lists the quotas and limits that apply to Network Connectivity Center and Router appliance.
To change a quota, see requesting additional quota.
A quota restricts how much of a particular shared Google Cloud resource your Cloud project can use, including hardware, software, and network components.
Quotas are part of a system that does the following:
- Monitors your use or consumption of Google Cloud products and services.
- Restricts your consumption of those resources for reasons including ensuring fairness and reducing spikes in usage.
- Maintains configurations that automatically enforce prescribed restrictions.
- Provides a means to make or request changes to the quota.
When a quota is exceeded, in most cases, the system immediately blocks access to the relevant Google resource, and the task that you're trying to perform fails. In most cases, quotas apply to each Cloud project and are shared across all applications and IP addresses that use that Cloud project.
Many products and services also have limits that are unrelated to the quota system. These are constraints, such as maximum file sizes or database schema limitations, which generally cannot be increased or decreased, unless otherwise stated.
This section lists quotas that apply to Network Connectivity Center and Router appliance.
Network Connectivity Center quotas
Quotas that apply to network routes for Cloud Router also apply to routes for Network Connectivity Center hubs and spokes. For more information, see Cloud Router Quotas.
|Number of VPN tunnel spokes||Quota||For HA VPN only and for each project in the specific region|
|Number of VLAN attachment spokes||Quota||For each project in the specific region|
|Number of Router appliance spokes||Quota||For each project in the specific region|
Router appliance quotas
Quotas that apply to network routes for Cloud Router also apply to routes for Router appliance spokes attached to Network Connectivity Center hubs.
For more information, see Cloud Router quotas.
This section lists limits that apply to Network Connectivity Center and Router appliance.
Network Connectivity Center limits
Network Connectivity Center enforces the following usage limits.
|Number of hubs that a project can have||1|
|Number of VPN tunnels that can be linked to a spoke||8|
|Number of VLAN attachments that can be linked to a spoke||6|
|Number of router appliance instances that can be linked to a spoke||8|
Router appliance limits
The following limits for Cloud Router also apply to Router appliance:
- The maximum number of Cloud Routers per combination of VPC network and region
- The maximum number of BGP peers for each Cloud Router in a given VPC network and region
For more information, see Cloud Router limits.
Network Connectivity Center enforces quotas on resource usage for various reasons. For example, quotas protect the community of Google Cloud users by preventing unforeseen spikes in usage. Quotas also help users who are exploring Google Cloud with the free tier to stay within their trial.
All projects start with the same quotas, which you can change by requesting additional quota. Some quotas may increase automatically based on your use of a product.
To view quotas or request quota increases, Identity and Access Management (IAM) principals need one of the following roles.
|Check quotas for a project||One of the following:|
|Modify quotas, request additional quota||One of the following:|
Checking your quota
- In the Cloud Console, go to the Quotas page.
- To search for the quota that you want to update, use the Filter table. If you don't know the name of the quota, use the links on this page instead.
gcloud command-line tool, run the following command to
check your quotas. Replace
PROJECT_ID with your own project ID.
gcloud compute project-info describe --project PROJECT_ID
To check your used quota in a region, run the following command:
gcloud compute regions describe example-region
Errors when exceeding your quota
If you exceed a quota with a
gcloud outputs a
quota exceeded error
message and returns with the exit code
If you exceed a quota with an API request, Google Cloud returns the
following HTTP status code:
HTTP 413 Request Entity Too Large.
Requesting additional quota
To increase or decrease most quotas, use the Google Cloud Console. Some quotas can't be increased above their default values.
For more information, see the following sections of Working with quotas:
- In the Cloud Console, go to the Quotas page.
- On the Quotas page, select the quotas that you want to change.
- At the top of the page, click Edit quotas.
- Fill out your name, email, and phone number, and then click Next.
- Fill in your quota request, and then click Done.
- Submit your request. Quota requests take 24 to 48 hours to process.
Each quota represents a maximum number for a particular type of resource that you can create, if that resource is available. It's important to note that quotas do not guarantee resource availability. Even if you have available quota, you can't create a new resource if it is not available.
For example, you might have sufficient quota to create a new regional, external IP address
us-central1 region. However, that is not possible if there are no
available external IP addresses in that region. Zonal resource
availability can also affect your ability to create a new resource.
Situations where resources are unavailable in an entire region are rare. However, resources within a zone can be depleted from time to time, typically without impact to the service level agreement (SLA) for the type of resource. For more information, review the relevant SLA for the resource.
