2. Use one of the following examples:

   • To list and view details of all routing tables for a VPC:

     data "ibm_is_vpc_routing_tables" "example" {
       vpc = ibm_is_vpc.example.id
     }
     

     For more information about the ibm_is_vpc_routing_tables resource, see the Terraform Registry.

   • To retrieve a single routing table specified by the identifier:

     data "ibm_is_vpc_routing_table" "example_routing_table" {
       vpc                 = ibm_is_vpc.example_vpc.id
       routing_table     = ibm_is_vpc_routing_table.example_rt.routing_table
     }
     

     For more information about the ibm_is_vpc_routing_table resource, see the Terraform Registry.

   • To retrieve the default routing table for the VPC specified by the identifier:

     data "ibm_is_vpc_default_routing_table" "example" {
       vpc = ibm_is_vpc.example.id
     }
     

     For more information about the ibm_is_vpc_default_routing_table resource, see the Terraform Registry.
