Route Table

Available in VPC

You can define network paths for resources in a VPC in a route table. Routes, or routing rules, are added by specifying the next hop based on the destination address. Associating a route table with a subnet affects communication for resources within that subnet. The detailed features of the Route Table are as follows:

• Each subnet has one route table applied, and multiple different subnets can be associated with the same route table.
• Depending on your intended use, you can create public route tables and private route tables.
  • Public route table: It can be associated with a public subnet, and rules for internet communication through the Internet Gateway (IGW) and LOCAL rules for VPC internal communication are automatically added.
  • Private route table: You can associate it with a private subnet, and the system automatically adds LOCAL rules for VPC internal communication.
• When you create a VPC, the system automatically creates a default route table. You cannot delete the default route table.

Route table interface

The following describes the basic components for using Route Table:

Component	Description
① Menu name	Currently confirmed menu name, the number of operating route tables.
② Basic features	Create route tables and refresh the route table interface.
③ Post-creation features	Configure associated subnets, configure routing rules, and delete active route tables.
④ Search bar	Enter search keywords and click to search for the item.
⑤ Search filter	Specify the route table scope to view.
⑥ Route table list	View the list of created route tables and their details.

   • VPC: Select the VPC to use with the route table.
   • Subnet support type: Select the subnet type to use with the route table.
     • When you select Public , you can apply it to the target VPC’s public subnets. When you select Private , you can apply it to the target VPC’s private subnets.
5. Click [Create].
6. When the Request Route Table popup appears, review the request details and click [OK].
7. In the Route Table interface, check the status of the created route table in the route table list.

   • Target Type: Select the type of the next hop for communication with the destination.
     • LOCAL: A default endpoint provided to configure communication between resources. You cannot create or delete it manually.
     • IGW: An Internet Gateway that serves as a gateway for internet communication. It appears only in public route tables, and you cannot create or delete it manually.
     • NATGW: A NAT Gateway that you create when outbound internet communication is required from a private subnet.
     • VGW: A Virtual Private Gateway that serves as an endpoint for Cloud Connect dedicated lines or IPsec VPNs configured to communicate with on-premises servers.
