Creating a Custom Route Table

Scenarios

A VPC automatically comes with a default route table. If the default route table cannot meet your service requirements, you can create a custom route table and associate subnets with it to control traffic in and out of the subnets.

Notes and Constraints

By default, the quota for custom route tables is 0. To create custom route tables, apply for a quota increase first.

Procedure

1. Go to the route table list page.
2. In the upper right corner, click Create Route Table. On the displayed page, configure parameters as prompted.
