   Default Route Table Association	Optional Enabling Default Route Table Association can simplify network configurations. After this function is enabled: Select a route table for Default Association Route Table. If you create an attachment to this enterprise router, the attachment will be automatically associated with the default association route table. After the association: Packets from the attachment are forwarded through the routes specified in the associated route table. If the type of the attachment is peering connection, virtual gateway, or VPN gateway, the attachment automatically learns routes from the enterprise router. For more types of attachments that support route learning, see How Enterprise Routers Work. If the type of the attachment is VPC, you need to add routes to the route table of the VPC for traffic to route through the enterprise router.	Enable
   Association Route Table	Optional If you enable Default Route Table Association, select a route table for Association Route Table. You can select a custom route table. If you do not select a route table, the system will create a route table named defaultRouteTable as the default association route table.
