subnet Length
Length of the IPv4 subnet mask. Allowed values: - 29 (default) - 30 The default value is 29, except for Cross-Cloud Interconnect connections that use an InterconnectRemoteLocation with a constraints.subnetLengthRange.min equal to 30. For example, connections that use an Azure remote location fall into this category. In these cases, the default value is 30, and requesting 29 returns an error. Where both 29 and 30 are allowed, 29 is preferred, because it gives Google Cloud Support more debugging visibility.
