ModifyTransitGatewayVpcAttachmentRequestOptions
Describes the options for a VPC attachment.
Types
Properties
Enable or disable support for appliance mode. If enabled, a traffic flow between a source and destination uses the same Availability Zone for the VPC attachment for the lifetime of that flow. The default is disable.
Enable or disable DNS support. The default is enable.
Specifies whether IPv6 support is enabled for the attachment. When enabled, the transit gateway network interface receives an IPv6 address. When you enable route propagation, IPv6 VPC CIDRs propagate to the transit gateway route tables. When disabled, the network interface does not receive an IPv6 address, and IPv6 routes do not propagate. The setting does not filter IPv6 traffic.
Enables you to reference a security group across VPCs attached to a transit gateway to simplify security group management.
