Overview

Represents a Subnetwork resource.

A subnetwork (also known as a subnet) is a logical partition of a Virtual Private Cloud network with one primary IP range and zero or more secondary IP ranges. For more information, read Virtual Private Cloud (VPC) Network.

Instance Attribute Details

#allow_subnet_cidr_routes_overlap ⇒ ::Boolean

Returns Whether this subnetwork's ranges can conflict with existing custom routes. Setting this to true allows this subnetwork's primary and secondary ranges to overlap with (and contain) custom routes that have already been configured on the corresponding network.

For example if a static route has range 10.1.0.0/16, a subnet range 10.0.0.0/8 could only be created if allow_conflicting_routes=true.

Overlapping is only allowed on subnetwork operations; routes whose ranges conflict with this subnetwork's ranges won't be allowed unless route.allow_conflicting_subnetworks is set to true.

Typically packets destined to IPs within the subnetwork (which may contain private/sensitive data) are prevented from leaving the virtual network. Setting this field to true will disable this feature.

The default value is false and applies to all existing subnetworks and automatically created subnetworks.

Returns:

#ipv6_gce_endpoint ⇒ ::String

Returns Output only. [Output Only] Possible endpoints of this subnetwork. It can be one of the following:

- VM_ONLY: The subnetwork can be used for creating instances and
IPv6 addresses with VM endpoint type. Such a subnetwork gets external IPv6
ranges from a public delegated prefix and cannot be used to create NetLb.
- VM_AND_FR: The subnetwork can be used for creating both VM
instances and Forwarding Rules. It can also be used to reserve IPv6
addresses with both VM and FR endpoint types. Such a subnetwork gets its
IPv6 range from Google IP Pool directly.

Check the Ipv6GceEndpoint enum for the list of possible values.
