Method Details

getAmazonSideAsn

@Stability(Stable)
@Nullable
default Number getAmazonSideAsn()

A private Autonomous System Number (ASN) for the Amazon side of a BGP session.

The range is 64512 to 65534 for 16-bit ASNs. The default is 64512.

getAssociationDefaultRouteTableId

@Stability(Stable)
@Nullable
default String getAssociationDefaultRouteTableId()

The ID of the default association route table.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-transitgateway.html#cfn-ec2-transitgateway-associationdefaultroutetableid

getAutoAcceptSharedAttachments

@Stability(Stable)
@Nullable
default String getAutoAcceptSharedAttachments()

Enable or disable automatic acceptance of attachment requests.

Disabled by default.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-transitgateway.html#cfn-ec2-transitgateway-autoacceptsharedattachments

getDefaultRouteTableAssociation

@Stability(Stable)
@Nullable
default String getDefaultRouteTableAssociation()

Enable or disable automatic association with the default association route table.

Enabled by default. If DefaultRouteTableAssociation is set to enable, AWS Transit Gateway will create the default transit gateway route table.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-transitgateway.html#cfn-ec2-transitgateway-defaultroutetableassociation

getDefaultRouteTablePropagation

@Stability(Stable)
@Nullable
default String getDefaultRouteTablePropagation()

Enable or disable automatic propagation of routes to the default propagation route table.

Enabled by default. If DefaultRouteTablePropagation is set to enable, AWS Transit Gateway will create the default transit gateway route table.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-transitgateway.html#cfn-ec2-transitgateway-defaultroutetablepropagation

getDescription

@Stability(Stable)
@Nullable
default String getDescription()

The description of the transit gateway.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-transitgateway.html#cfn-ec2-transitgateway-description

getDnsSupport

@Stability(Stable)
@Nullable
default String getDnsSupport()

Enable or disable DNS support.

Enabled by default.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-transitgateway.html#cfn-ec2-transitgateway-dnssupport

getEncryptionSupport

@Stability(Stable)
@Nullable
default String getEncryptionSupport()

Enable or disable encryption support.

Disabled by default.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-transitgateway.html#cfn-ec2-transitgateway-encryptionsupport

getMulticastSupport

@Stability(Stable)
@Nullable
default String getMulticastSupport()

Indicates whether multicast is enabled on the transit gateway.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-transitgateway.html#cfn-ec2-transitgateway-multicastsupport

getPropagationDefaultRouteTableId

@Stability(Stable)
@Nullable
default String getPropagationDefaultRouteTableId()

The ID of the default propagation route table.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-transitgateway.html#cfn-ec2-transitgateway-propagationdefaultroutetableid

getSecurityGroupReferencingSupport

@Stability(Stable)
@Nullable
default String getSecurityGroupReferencingSupport()

Enables you to reference a security group across VPCs attached to a transit gateway (TGW).

Use this option to simplify security group management and control of instance-to-instance traffic across VPCs that are connected by transit gateway. You can also use this option to migrate from VPC peering (which was the only option that supported security group referencing) to transit gateways (which now also support security group referencing). This option is disabled by default and there are no additional costs to use this feature.

For important information about this feature, see Create a transit gateway in the AWS Transit Gateway Guide .
