Hi@akhtar,
You can use aws_route_table resources in your Terraform code. It will help you to create a routing table in your VPC. I have attached one example below for your reference.
resource "aws_route_table" "table" {
vpc_id = "${aws_vpc.main.id}"
route {
cidr_block = "0.0.0.0/0"
gateway_id = "${aws_internet_gateway.gw.id}"
}
tags = {
Name = "MyRoute"
}
}
