public sealed class InterconnectAttachmentConfigurationConstraints : IMessage<InterconnectAttachmentConfigurationConstraints>, IEquatable<InterconnectAttachmentConfigurationConstraints>, IDeepCloneable<InterconnectAttachmentConfigurationConstraints>, IBufferMessage, IMessage
[Output Only] Whether the attachment's BGP session requires/allows/disallows BGP MD5 authentication. This can take one of the following values: MD5_OPTIONAL, MD5_REQUIRED, MD5_UNSUPPORTED. For example, a Cross-Cloud Interconnect connection to a remote cloud provider that requires BGP MD5 authentication has the interconnectRemoteLocation attachment_configuration_constraints.bgp_md5 field set to MD5_REQUIRED, and that property is propagated to the attachment. Similarly, if BGP MD5 is MD5_UNSUPPORTED, an error is returned if MD5 is requested.
Check the BgpMd5 enum for the list of possible values.
public RepeatedField<InterconnectAttachmentConfigurationConstraintsBgpPeerASNRange> BgpPeerAsnRanges { get; }
[Output Only] List of ASN ranges that the remote location is known to support. Formatted as an array of inclusive ranges {min: min-value, max: max-value}. For example, [{min: 123, max: 123}, {min: 64512, max: 65534}] allows the peer ASN to be 123 or anything in the range 64512-65534. This field is only advisory. Although the API accepts other ranges, these are the ranges that we recommend.
