Step 4: Create a Route Table
Scenarios
Each public NAT gateway requires its unique route table. Create the second route table for the VPC.
If the custom route table quota is insufficient, to increase the route table quota.
Prerequisites
A route table can be created in the VPC.
Procedure
- Log in to the management console.
- Click Service List in the upper left corner. Under Network, select Virtual Private Cloud.
- In the navigation pane on the left, choose Route Tables.
- In the upper right corner, click Create Route Table. On the displayed page, configure required parameters.
Table 1 Parameter descriptions Parameter
Description
Example Value
Name
(Mandatory) The name of the route table
Enter up to 64 characters. Only letters, digits, underscores (_), hyphens (-), and periods (.) are allowed. Spaces are not allowed.
rtb-001
VPC
(Mandatory) The VPC that the route table belongs to
vpc-001
Description
(Optional) Supplementary information about the route table
Enter up to 255 characters. Angle brackets (<>) are not allowed.

Route Settings
Routes contained in the route table
You can add a route when creating the route table or after the route table is created.
You can click + to add more routes.
N/A
- Click OK.
A message indicating that subnets can now be associated with the created route table is displayed. Perform the following steps to associate the other subnet of the VPC with the route table:
- Click Associate Subnet.
The Associated Subnets tab is displayed.
- Click Associate Subnet and select the second subnet created in Step 1: Create a VPC and Two Subnets.
- Click OK.
- Click Associate Subnet.
