Request parameters

Parameter Type Required Example Description
Action String Yes CreateRouteTable

The operation that you want to perform. Set the value to CreateRouteTable.

RegionId String Yes cn-zhangjiakou

The region ID of the virtual private cloud (VPC) to which the route table belongs.

You can call the DescribeRegions operation to query region IDs.

VpcId String Yes vpc-bp1qpo0kug3a20qqe****

The ID of the VPC to which the custom route table belongs.

If a VPC contains an Elastic Compute Service (ECS) instance of the following instance types, you cannot create a custom route table for the VPC:

ecs.c1, ecs.c2, ecs.c4, ecs.c5, ecs.ce4, ecs.cm4, ecs.d1, ecs.e3, ecs.e4, ecs.ga1, ecs.gn4, ecs.gn5, ecs.i1, ecs.m1, ecs.m2, ecs.mn4, ecs.n1, ecs.n2, ecs.n4, ecs.s1, ecs.s2, ecs.s3, ecs.se1, ecs.sn1, ecs.sn2, ecs.t1, and ecs.xn4.

To create a custom route table, you must upgrade the instance specification. For more information, see Upgrade the instance types of subscription instances and Change the instance type of a pay-as-you-go instance.

Note If your VPC contains one or more ECS instances of the specified instance types and uses a custom route table, you must upgrade the ECS instances. Otherwise, the custom route table cannot work as expected.
