# Direct Interconnect VLAN Attachment and router

This module allows creation of a VLAN attachment for Direct Interconnect and router (router creation is optional).

## Examples

### Direct Interconnect  VLAN attachment using default parameters for bgp session and router

```hcl
module "vlan-attachment-1" {
  source         = "./modules/net-interconnect-attachment-direct"
  project_id     = "dedicated-ic-5-8492"
  region         = "us-west2"
  router_network = "myvpc"
  name           = "vlan-604-x"
  interconnect   = "https://www.googleapis.com/compute/v1/projects/mylab/global/interconnects/mylab-interconnect-1"
  peer = {
    ip_address = "169.254.63.2"
    asn        = 65418
  }
}
# tftest:modules=1:resources=4
```
