   Table 1 Parameter description

   Parameter	Setting	Example Value
   Name	Mandatory If you want to change the name of the enterprise router, enter a new name. The name: Must contain 1 to 64 characters. Can contain letters, digits, underscores (_), hyphens (-), and periods (.).	er-test-01
   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, a route table named defaultRouteTable will be automatically created as the default association route table. If there is already a route table named defaultRouteTable, no route table will be created.	er-rtb-b931
   Default Route Table Propagation	Optional Enabling Default Route Table Propagation can simplify network configurations. After this function is enabled: Select a route table for Association Route Table. If you create an attachment to this enterprise router, the attachment will be automatically propagated to the default propagation route table. After the propagation: If it is a peering connection, virtual gateway, or VPN gateway attachment, the enterprise router automatically learn routes from the attachment. For details about route learning of more types of attachments, see How Enterprise Routers Work. If the type of the attachment is VPC, the enterprise router uses the VPC CIDR block as the destination of a route.	Enable
   Propagation Route Table	Optional If you enable Default Route Table Propagation, select a route table for Propagation Route Table. You can select a custom route table. If you do not select a route table, a route table named defaultRouteTable will be automatically created as the default propagation route table. If there is already a route table named defaultRouteTable, no route table will be created.	er-rtb-b931
   Auto Accept Shared Attachments	Optional As the owner, you can share your enterprise router with the principals. These principals can create attachments for your enterprise router. If you do not select this option, you must manually accept attachments to this enterprise router from the accounts that this enterprise router is shared with. If you select this option, the attachments from the accounts that this enterprise router is shared with will be automatically accepted. For details, see Sharing Overview.	Enable
